Yep: Exactly how it sounds.
I woke up around 4am last night while sleeping on my side to feel two arms wrap around me and pull close. At first I thought it was sweet, then realized no one was in bed with me. I started thinking "I should be absolutely terrified by this" even though I wasn't terrified. I remember thinking my arms probably just fell asleep, so I lifted them up. But as I lifted them up, I felt the arms of what's behind me also be pushed up - like I felt the extra weight. The arms were bare while I was in a T-Shirt. I remember thinking "Okay, I 100% feel this," and trying to speak. It was difficult, but I was able to say "Let go of me." I remember seeing light under my bedroom door and realizing I'm going to be up all night scared, but as I thought about it I probably fell asleep, because next thing I knew I opened my eyes and could speak and think clearly.
Again, I wasn't scared, but I didn't remember it happening until 12 hours after I woke up. Thinking about it creeps me out, but just thought I'd share and I was wondering if you've had similar experiences.
I haven't done any psychedelics recently, but I took DMT around this time last year. That was a positive, non-scary experience.
In terms of sleep pattern, I had somehow taken a three hour nap between 6pm and 9pm, then fell asleep at midnight, which could have screwed things up.
I also fell asleep thinking about body pillows and how much more comfortable it is to sleep when you're cuddling someone.
I've only had an experience like this once before, where before falling asleep I was praying and felt a presence push down on my back (while laying on my stomach) to "taunt" me.
