Hypnagogic imagery and voices can occur not just moments before/after sleep but also during the waking days. It has been shown that REM sleep deprived subjects can experience auditory and visual hallucinations whilst apparently awake. For case studies see accounts of Randy Gardner and Peter Tripp who both underwent sleep deprivation exercises for charity.
I have bipolar disorder (aka manic-depression) and one of the symptoms of the manic phase is sleeping less or not sleeping at all, as well as hallucinations. In my experience of mania, when I sleep it seems that I miss out on the dream phases (I forget what they're called), and I will only sleep about 3-4 hours. I drop off and wake up instantly, and it feels like no time has passed in between. I'm not sure if this is connected to the hallucinations, but I've often wondered.
Even when 'normal' I've had plenty of experiences of hearing voices of the hypnogogic type, like people have mentioned here, but don't think much of them mostly as whatever is said never seems particularly relevant to anything.
The more interesting experiences I don't know how to explain, and some quite probably are caused by my illness. (Definitely, according to my shrink, but I like to keep an open mind. :blah: ) Once, I had an invisible friend/imaginary friend/spirit guide that was with me for several months. She had a name, personality and even a sense of humour! She was never intrusive, although she would pop up unexpectedly with comments about things from time to time, and she would always leave if I wanted her too, so I never minded her being around. And even though I hadn't been diagnosed at this time, I never worried too much about being "nuts" 'cause there didn't seem to be any harm in it.
A couple of experience occured after my aunt died. The day she died (and I was already aware that she had, btw) I was (obviously) very upset, and I quite clearly heard her voice saying: "It's OK, I'm happy here." The next day I was reading a Terry Pratchett Discworld book, that has the character of Death, the Grim Reaper, and idlely wondered if "Death" had come for my aunt when she died. I heard a male voice that I've never been able to identify, say "No, her grandmother did." When I told my family about this I was able to get an explanation from them, that my aunt had been very close to her maternal grandmother (who had died before I was born). I don't recall ever knowing this. Anyway, nuts or not, this was a great comfort to grieving relatives.
A week or so later I heard my aunt's voice again saying "Don't let him throw out the ... " and I didn't catch what 'he' wasn't supposed to throw out. Very frustrating. It turns out that my uncle had begun sorting out her possessions and was giving things away to relatives. I didn't hear her again, so can only assume she was happy with the way things were disposed of.
Last year (2 years after she died), my grandmother (her mother) was going through a period of depression that she still won't admit to, and the rest of the family believe was related to her daughter's death. She'd been in very bad health and we were afraid that she wasn't going to be with us for much longer. One day in church she heard my aunts voice saying something similar to what she'd said to me: "It's OK, I'm happy here." She recovered quite quickly after that.
One explanation could be that it is the brain's way of providing comfort during the grieving process, but, again, I like to keep an open mind.
Anyway, that's enough stories for now, if I keep going I'll be hear all night. I hope this makes sense, 'cause it's late and I'm very sleepy. I'd better head off to be 'cause the voices are gathering!!! :eek!!!!: :eek!!!!: :eek!!!!:
