Most of the faeries that we see (and that other people notice in our home) look like blurry spheres of light. Usually–probably 95% of the time–I see them as white or very pale yellow. Sometimes they are pink, or blue, or darkish grey.

I don’t think that the darker ones are “bad”. They’re just a different color, or perhaps I just perceive them that way.

what faeries would look like
over my sewing table Because they’re not usually distinct, it’s difficult to describe the exact size of them. On average, I’d guess that they range between the size of a ping pong ball, and the size of a tennis ball. (Remember: These are not real photos - I created them to show you what I see.)
what faeries would look like,
visiting Mona at the Louvre These spheres appear in daytime and night, with no apparently “favorite” time to appear.Sometimes they blink in and out like a light switch was turned on and off. This is rare. Usually, they seem to fly into another dimension, and fade from sight gradually.

They are not brighter at night.They move at varying speeds. They do not move when my eye does, as a “floater” would.

Sometimes they hover for a split-second. Usually, they’re moving.

Sometimes you’ll see them out of the corner of your eye. Usually you’ll see them directly.

They are clearly part of the environment. They don’t appear to fly through furniture, but fly around it. I never confuse them with a reflection on my reading glasses.

They only vaguely resemble reflections off passing cars. However, they aren’t usually such distinct shapes as reflections are.

Sometimes, faeries fly between two of us, when we’re talking. This is what causes skeptical visitors to ask, “What’s that?”

However…

If you see lights like this out of the corner of your eye, and they seem to move when your eye does, or, if you see “fireworks” out of the corner of one eye, see your doctor immediately. Some medical conditions can cause this type of visual impression; many of them are easiest to treat if discovered early.
