A black hole entity?

[Durward]

I dont get it to be honest. Is there some metapher im not getting?
Because theres no truth to that whatsoever.

And that's exactly what I was going to ask you, in a DM to avoid the obvious...

This was really weird encounter so I want to ask if anyone happened to stumble upon this weirdo entity. It was astral one presumably. I was dreaming when I "fake" woke up to see it by my bed, very close to me. It was mass of blackness in basic human shape, but well defined. It was black and felt extremely empty, like a vacuum or black hole that was pulling stuff in. It definitely was pulling in my breath and I was struggling to breathe. I tried to say "say your name," but sound was sucked with the breath. At first moment I was neutral to it, because I didn't know but since it kept giving me such problems breathing and said nothing, I started fighting back, I started pushing it away with one hand, I moved it a little. It was possible to touch it. Then I managed to really move, lifted my other hand and grabbed it's neck... or I was aiming for that. I woke up and my hand, my physical hand, actually grabbed nothing but air.

It must had go away, the surrounding around me felt like the brightness started to go up and density of energy was going up as well for few moments.

Weird is that I felt nothing from the being myself, no emotions. Seems like I remained calm all the time...

But what the f was that? I would not call it a vampire, it seemed rather like black hole than bloodsucker...

While this does sound like some sort of parasitic entity I feel obligated to point out that your experience sounds extremely similar to something known as "sleep paralysis". Shortness of breath, inability to move and hallucinations are pretty common symptoms of the experience and some researchers think some historical reports of spirits attacking people during their sleep is due to this phenomenon. If I recall correctly it has to do with most of the brain "waking up" suddenly while leaving the parts that control your limbs turned off. That part of your nervous system is normally dozing off to stop you from bruising yourself in your sleep or sleepwalking but it can malfunction sometimes, like in chronic sleepwalking.

The theory is that when someone enters this state the brain starts to panic at the thought of being unable to move and that combined with your sleepy state produces a kind of waking nightmare where your mind conjures up this narrative of being attacked as a justification for what's currently happening, hence the hallucination of some sort of nebulous entity being present. The choking sensation is a mixture of your chest muscles being too tensed up from the terror and the muscle paralysis. The brain then naturally connects these two things together into the narrative of "something is choking me in my sleep".

Stress seems to have a big correlation with it, and I know this first hand because I had a similar experience to yours when I was in a period of intense depression on top of a recent funeral experience and had to sleep in the house of some relatives I didn't like. That night I suddenly woke up without being able to move or open up my eyes at all. I could feel what I thought was someone lying on top of me with hands on my chest and whatever it was was snarling at me like a beast. Strangely, I remember my sleeping self thinking it was all a bit too funny and smiling through it all even though when I actually woke up from it I was absolutely terrified. Awful week that was.

I'm not saying you and me didn't experience something supernatural but it's good to have the mundane explanations for such things in mind. I'm interested to know you also felt calm through it, that was very surreal for me as well but it really didn't feel like me at all. The closest I ever felt to that was being strangely calm when someone robbed me for my cellphone while I handed it over to them and then feeling all the stress build up moments after it was over.
