It came again

I don't know anymore, is it alien or is it demonic or is it just something looking for some sort of self gratification of the type we don't understand ... It never visibly harms and doesn't always alert...but it is there. It is not I repeat in no way sleep paralysis. After waking from a potential sleep paralysis moment it came back. I had stood up to shake it off and when I laid back down it returned while I was awake, I saw nothing but felt it's presence it was cold so cold. It was in the air around me thick like a thick vibrational energy. It left and I was left standing.
