For lack of something better to do: Do you guys experience any sort of hallucinations?
I both hear faint auditory hallucinations (like my alarm clock, cell phone, etc) and see bright flashes of light when I
close my eyes in a dark room (which means that it appears much darker when I open my eyes than when I leave them closed, which is why I often get dry eyes when I sleep) frequently.
Although not as often, I've also experienced loud bangs when I've been sleepy.
