What on earth... I've never heard of hypnogogia. I just looked that up to discover hypnopompic... auditory hallucinations as you transition from sleep to waking up. I haven't constantly suffered this, but at periods in the last 5 years, I have often woken with a jump and an impending sense of dread to either the sound of a doorbell, or my ex yelling my name. In both cases, I know these were hallucinatory, the doorbell I have installed doesn't make the same sound as the doorbell I hear as I wake, nor has my ex been in my presence at the time I heard her calling my name. I had no idea this was a thing, I thought I was just going crazy, lol. So thanks for introducing me to these "conditions(?)" Perhaps I am still crazy, but at least there's a name for it :D
There's a word in the Sami language (a culture indigenous to parts of Scandinavia) that describe the state between being awake and asleep: "Adjágas".
It's been somewhat impotently translated as "slumber" - but it's more akin to what gp describe. I'm sure many native American languages have similar concept.
Yeah, a friend told me about that a while ago. He was pretty freaked out and worried it might be some kind of psychosis!
Don't think you have to worry. I haven't had any issues with my mental health for 8 years, beyond maybe periods of high work stress, and it's appeared at night often since then.
