I've posted before about a debilitating nexus of symptoms I experience every day that seems to be inexerably linked, if not caused by, accompanying poor quality, unrefreshing, and fragmented sleep.
In an effort to throw more things at a wall to see what sticks, I've been trying biphasic sleep this week. That is to say, after I awaken for the 2nd or 3rd time, after around 4-5 hours of sleep, I get up and go do something quiet and relaxing for an hour or so, then go back to sleep. However, when I go back to sleep, I have been experiencing some wierd stuff for hours at a time that is reminding me that these wierd phenomena are not new for me, and might explain part of what is wrong with my sleep.
It first starts with me slipping into stage-1 sleep after about 5-10 minutes, where my mind goes totally blank, and my body and breathing are both quite relaxed. However, instead of slipping into unconcious, stage 2 sleep, my "vision" fills with random imagery such as faces I don't recognize, fractal shapes, and strange maze-like landscapes that I view from above -- all with an artificial, blue-green hue to them. This is also accompanied with disembodied voices and random sentences filling my awareness that sort of surprise me into a slightly more aware state. This sounds like hypnagogic hallucinations so far, although a different sort than full-blown sleep-paralysis, which I have experienced before in the past, in that I don't feel any sort of dread, massive body weight, or presence in the room. Sometimes this is accompanied by myoclonic jerks, which are much more common when I'm sleep deprived, but I'd say that hypnagogic hallucinations are a nightly thing.
After a while, if I can't pass beyond this stage-1 sleep, I fall into a psuedo-dreaming state where I vaguely know I'm not asleep, and am slightly conscious of the fan in my room, but am dreaming none-the less. I almost feel like I'm lucid dreaming and can indeed, interact with my dreams in a way that's hard to describe. However, in this psuedo-dreaming state, the back of my head (I'm laying on my side) fills with a pressure of sorts, as though its inflating, I feel my eardrums fill with a sensation one would get when yawning, and after a few seconds of these head sensations, some impulse, similar to a violent involuntary shiver, with sensation of coldness shoots from the back of my head down my spine. This doesn't really shock me awake, though, and I continue in the psuedo dreaming state with the pressure in the back of my head eventually shooting back down my spine. The things I describe in this paragraph can go on for hours, or can fade away into a very restless REM-filled sleep where I am actually asleep and know I am asleep. My body also feels uncomfortably warm when these things are happening, even if the room is not, which is interesting because my body temperature is always 1-2-degrees below normal and otherwise, I always feel cold. I usually wake up with a headache and musculoskeletal pain that makes me joke to myself that I got hit by a truck while I was sleep walking. Often the experiences in this paragraph also happen to me when I'm in the process of falling back asleep without having gotten out of bed, but I transition into sleep much more quickly if I don't get out of bed.
Sometimes the hypnagogic hallucinations can be accompanied by the electrical sensations originating from my spine, along with spatial hallucinations similar to being pulled through the air, in such a way that isn't filled with any of the musular paralysis or dread of sleep paralysis. Sometimes, the disembodied voice hallucinations actually communicate coherent ideas to me and I respond with my inner voice, to which the disembodied voice continues the "conversation" for an indeterminate time that "feels" like quite 15-20 minutes. This is the kind of bizarre shit that is associated with OBE experiences and psychic phenomena, but could all of these wierd things I describe be a form of nocturnal epilepsy?
It's worth noting that this stuff happens when I'm trying to fall asleep and sleep isn't coming easy for me. All or some combination of these things happen to me every time I try to take a nap outside of my normal circadian rhythm. I say "try" to take a nap because I can't remember the last time I have ever actually fallen asleep in a nap - despite being exhuasted enough to want to. In the past, sleeping in an uncomfortable place, indigestion, or being on tramadol, amphetamines or caffeine and trying to sleep are sure ways to experience some or all of this strange phenomena. In particular, stimulants have a way of inducing the pseudo-dreaming state that is heavy on disembodied voice "conversations" and that state of sleep-borne altered consciousness that is free of the electrical impulses. In the past, alcohol withdrawal has made for hours of hypnic jerks, but I'm not on any medications, nor am I withdrawaling from anything.
When I had a polysomnogram, I had a spontaneous arousal index of 12 - which is also interesting in that I feel like there's some endogenous source that pulls me out of deeper stages of sleep and also shocks me awake, sometimes just seconds into REM sleep. I can recall this stuff going back to childhood. I used to think the electical discharge down my spine was some sort of wierd talent I had, or that my house(s) were always just haunted. Later on, I thought the psuedo-dreaming state was just restless REM sleep and that I was perhaps dreaming the nocturnal-seizure like things. However, like I said, it's been happening to me this week, and remarkably so last night where the seizure-like activity went on, over and over again, for what felt like over an hour. The experiences used to scare me, but now I just view them as a curious nuisance and am not troubled. Instead, I'm wondering if this could be a valuable clue as to what is happening in brain.
