Sporadic deeply uncomfortable/nauseating sensation often when half asleep

[Auron]

Long shot, but I wanted to see if this struck a chord with anyone.

Something that has happened to me all my life very very intermittently with no explanation, but too seldom and short lived to make a note of it or explain it to anyone.


So this usually happens in the middle of the night while dozing or while being halfway between asleep and awake.
I will be lying in bed, and suddenly I will feel deeply unusual. It might typically start with a kind of “foamy/plasticy/rubbery feeling in my sinuses, as I breathe, and that feeling will spread out into my entire body.

It will feel like my body is made out of a strange material, and that I am perhaps speeding trough space, or speeding through time; it feels disturbing and nauseating.
What’s more, while even just staying still and breathing is nauseating and dizzying, this is many times worse if I attempt to move or shift position.

It is always alarming when it happens (like, emotionally) and it conjures up previous instances of it happening, like a kind of “oh god, not this again” it happens randomly in bed while dozing, and it comes and passes in maybe a minutes or two, and it might not happen for years in between instances.

I have no idea what it is or if it is dispraxia related.

I wonder if you're being treated for high blood pressure. I had similar episodes (at midday ) and it turned out my blood pressure had gone abnormally low. The problem has been much alleviated by my GP adjusting my antihypertensive medications. worth getting BP checked in any case.
Hope this may be helpful.

No. My blood pressure is typically OK.

Like, my first guess is it’s an unusual presentation of sleep paralysis? But the accompanying mind sensation is unpleasant and familiar.

In the very rare instances I have experienced (confirmed) sleep paralysis, it’s felt completely different, and not at all related.
