Did Kafka experience something like this before writing The Metamorphosis?
Sounds to me like you either had an out-of-body experience (astral projection) or you might have been lucid dreaming or somewhere in between. Sometimes when astral projecting you’ll appear or be in a familiar place (bed room or bathroom) and experience dream-like phenomena while experiencing conscious thought. Very cool stuff.
IndigoRain, you may be having episodes of Sleep Paralysis, another sleep disorder. I used to get that, which was apparently triggered by my sleep apnea. Once my apnea was being properly treated, the waking paralysis went away. While what you describe is not identical to the experience of the poster in the thread I linked, two key factors strike me as similar: The feeling that something is menacing you and yelling yourself awake – I had to do that fairly often. I live in a duplex and it pissed my neighbors off to no end.
Night terrors. Not saying this is going to reoccur but it sounds like you had an episode similar to what happens in this disorder. Probably just a passing thing, but if it starts happening more…
Thanks for the answers. Those terms you gave me are the sort of things I was looking for. I wondered if there was a name for that sort of thing and also if it perhaps matched up with some symptoms of any psychiatric syndrom related to alienation from self but it seems like that is not the case, which is nice to hear.
