What Happens if You Sleep Next To A Mirror?

(Last Updated On: September 24, 2022)

Mirrors are a mainstay of many bedrooms, providing us with a place to brush our hair, apply makeup, check outfits, etc. Knowing where to place a mirror for maximum impact is important, as the wrong positioning can disturb your sleep.

Sleeping next to a mirror or having a reflective surface facing your bed is inadvisable. Light bouncing off mirrors can keep you awake at night, startle you or your pets, and cause hallucinations and sound echoes. So, always move or cover your mirrors overnight.

The relationship between mirrors and sleep is equal parts spiritual and scientific, so there are many reasons to avoid exposing yourself to reflective surfaces overnight. Always consider the proximity of mirrors when arranging bedroom furnishings.

Is it Bad to Have a Mirror Facing Your Bed?

According to feng shui, sleeping with a mirror beside your bed is a disaster.

If you’re unfamiliar with feng shui, it’s an eastern philosophy dedicated to strategically placing furnishings and belongings in the home to maximize balance.

The Journal of Evidence-Based Integrative Medicine describes feng shui as “therapy for the new millennium,” though naturally, it’s a personal choice whether you agree.

The basic philosophy of feng shui is as follows:

  • Every room has a commanding position, which is the area where you’ll spend the most time. In the bedroom, this will be your bed.
  • The commanding position should be as far from the door as possible, ideally at a diagonal angle with a clear line of sight.
  • The rules of feng shui involve balancing five elements: fire, water, wood, earth, and metal.

Mirrors represent water in this ideology, formless and reflective. Feng shui practitioners strongly advise against keeping mirrors by a bed for the following reasons:

  • Sleeping facing a reflection increases the likelihood of nightmares.
  • Allowing a reflection to face your bed invites a third person into a relationship, leading to strife.
  • Mirrors can drain personal energy and élan, causing insomnia.

To some, feng shui is an essential guiding principle in home decor.

Alternatives Locations for A Mirror

Before we move on from the philosophies of feng shui, mirrors aren’t considered problematic, but we need to consider where they’re placed.

Instead of beside your bed, apply mirrors to a bedroom using these criteria:

  • Use square or rectangular-shaped mirrors when possible.
  • Hang the mirror on a North or East-facing wall, ideally perpendicular to a wall. Never hang a mirror on a South facing wall.
  • Avoid hanging mirrors over sofas or chairs, though facing them is okay.
  • Avoid mirrors that obscure or distort your reflection or reflect on separate pieces, such as a mosaic.

If you adhere to these guidelines, you’ll enjoy a balanced and harmonious energy flow throughout your home. This should, naturally, lead to a comfortable and satisfying night of sleep.

Why Is It Bad to Sleep Next To A Mirror?

We could spend hours extolling theories laid out by feng shui practitioners as to why we should never sleep next to a mirror. Now is a good time to move away from philosophy and into the realm of science.

Regardless of whether you believe in and adopt the practices of feng shui in your everyday life, sleep experts recommend avoiding a mirror by your bed or facing it, such as on a ceiling.

When preparing the layout of a bedroom, consider the location of your bed and any mirrors as thoroughly as color schemes for the walls.

Reflected Light

Sleeping next to a mirror is invited any light that hits this surface to reflect into your eyes.

When light hits a mirror, it bounces back at the same angle. This will become an issue if you can’t keep your bedroom 100% pitch dark at night.

Slight slithers of light can cause havoc, such as streetlamps peeking through closed curtains. Unless you have blackout blinds, you’ll likely face at least some light pollution.

The idea of a little light may not seem like the end of the world at first, but it can become an issue.


It’s 6 am, the alarm has woken you, and you reluctantly lift your head from the pillow to shut it off. As you do so, you jump out of your skin – you’ve been exposed to your reflection before you’ve even had time to rub the sleep from your eyes.

Everybody is likely to be startled by any such vision. Our eyes need a few moments to adapt from night vision to natural daylight when we wake up. A mirror reflection can be a real wake-up call.


Looking at your reflection in dim lighting can play tricks on the eyes, forcing you to see an unfamiliar visage looking back at you.

Sometimes, these illusions will be distorted reflections of our visage. Some people also claim to see visions of supernatural beings, deceased family members, and other sights. All of these hallucinations will doubtless upset sleepiness.

According to Consciousness and Cognition, this is known as the Strange Face in the Mirror Illusion. These are essentially hallucinations – hardly something that will encourage a peaceful and restful night of sleep.

Of course, looking in a mirror with dim lighting is sometimes essential. When planned, you’ll be prepared for what you see. Peering into a mirror beside a bed, mainly due to spacial logistics, make a hallucination much likelier.

Echoes of Sound

It’s not just light that reflects when it hits a mirror. The same applies to sound waves. This will only apply if you sleep right beside a mirror. However, if you have a reflective surface next to your bed, any noise you make will be bounced straight back toward you.

This will be problematic for light sleepers, especially if you’re prone to snoring or sleep apnea. You may be able to sleep through the noise you make, but imagine if the din was doubled.

A partner who shares a bed may initially welcome the idea of snorers getting a taste of their own medicine, but they will suffer. Mirrors will replay snoring in stereo.

Disturbing Pets

Consider the impact of sleeping close to a mirror on any pets in your room. Sleeping with a dog on your bed is inadvisable, as this will likely disturb your sleep.

Cats and dogs often mistake their reflection for conspecifics, especially when young. This will cause significant excitement for your pet. A cat may grow territorial and attack the reflection or flee, while a dog may start barking and attempt to interact.

If this unfolds on your bed, you’ll be woken by the din at best. There’s also a pronounced risk that you’ll be scratched or bitten in any subsequent melee.

Should You Cover Your Mirror at Night?

Sometimes, it’s impossible to avoid sleeping next to a mirror.

Perhaps you have recently moved home and have yet to redecorate or are staying with a friend or family member. Hotels may also have mirrors by beds, though they should know better.

Whatever the reason, you don’t need to suffer the impact of sleeping beside a mirror. Cover the surface before attempting to sleep, and you’ll likely have a more restful night. The same applies to other reflective services, such as TV screens.

The easiest way to cover a mirror is by draping fabric over it. If the mirror is small, a scarf or item of clothing like a sweater will do the trick. Larger or full-length mirrors will need something equally substantial as a cover, such as a bath towel or coat.

How about longer-term solutions? For example, you may live in rented accommodation that contains a wardrobe with large, mirrored doors. Removing the closet will not be an option. Consider wallpapering over the mirrors if you can’t place the bed anywhere else.

One final option could be to obscure the mirror with frosted glass. This can usually be purchased from hardware stores with sticky-backed plastic, easily applied or removed as necessary. Remember that this still falls foul of feng shui advice if that matters to you.

It doesn’t matter if you believe in ancient philosophies about a room’s energy flow or not, as there’s enough evidence to back up the impact reflective surfaces have on the ability to sleep.

For quality rest, keep your bed away from mirrors or cover them before retiring for the night.
