Is hallucination one of the vicissitudes of age?

Sexual hallucinations is one the vices of old age.......

it was a light brown blur that crossed 20 feet of the room in under a second

Sounds like a bird.

Either, a small fast winged animal just flew across the room in front of me
or
I just hallucinated?

Could it have been a shadow of something outside? A bird flying past my window at the right time of day can send a blurred shadow flying across the room. Keeps startling me when it happens.
Or maybe it was just a fly or smaller insect just inches from your face, making it seem bigger?

Some moths overwinter as adults, in spaces resembling niches under loose bark etc - most can fly above 55F or so, although it takes them a while to warm up.
