I had night terrors as a child. Whispering voices in my ears that would get louder.
From 2015-to early 2018 sleep paralysis where I felt like I was literally dying, all worst fears hitting me at once and an evil presence in my room.
I’ve researched it a bit, many people describe the feeling of something sitting on their chest.
I think something is trying to take possession of you (us) while we are sleeping.
