>They are difficult to look at
Yes, during sleep paralysis they are always just out of my view off to the side. Like they are right beside me but I cannot turn to look at them. I know they are there. Sometimes I see them but always from a different angle or I see them but just a part of them like a head or a hand. But they are there for sure.

mhm, once I was able to get a clear view of one, it approached and knelt over me, bending down over me while I lay on my back, I could the weight of it and it was like pushing against a stone, usually in the dream state I can do what I want, only in sleep paralysis do I find myself seemingly helpless. As for the entity, I can only describe it as humanoid as in Op picrel, but a swirling black/blue smokey voidy stuff, it's hard to describe because it didnt make sense to look at. You could have something look like that in normal waking life, if that make sense.

pretty cool m8
description is spot on, appears in peripheral vision, pounces your face, looks hazy like it's a projection over reality 
the one I saw in particular had a face like a lamprey. oh and i wasn't asleep yet, literally just turned the lights off and it tried to jump me
