I've had sleep paralysis 3 times. When your lying face down in the bed it was ******* scary because I thought I was being raped. Had it another time but I was physically moved. My legs were slid off the bed. The other time I saw a shadowy figure. It is the most terrifying experience that any human can experience bar none. You can't move and can't shout mummy.
Hahaha I can't say I've ever felt penetration but each to their own
I will probably attract ridicule etc but a few years ago I was in London for work, weekend thing, put up in a very exciting travel lodge no expense spared. Girlfriend was at home in the flat herself.
Anyway, after doing my thing during the day, going out for a meal and drinks after I was still quite drunk when she woke me by calling during the night really upset, talking about getting "punched in the face" through her pillow that had woke her up and had left a bit of a red mark, tingling etc. Obviously I would normally treat it with the obvious scepticism like most people if it wasn't for how upset she had gotten, done my best to calm her down and confort her by now at this point I'm quite convinced something's happened if not a very realistic dream etc.
A few weeks later back home, can't quite remember how long exactly, I went to bed one night few hours after she'd went through and settled down. During the night at some point the same happened to me, I can only say I got punched in the face through the bed frame.
I sleep with one pillow lying sideways, flat along the mattress with my hand under my head and pillow and my head was forced up quickly as if I was looking into the room and fell back down again. I really felt it, felt warm. I am a light sleeper so most noises or twitches etc have me thinking quickly even then it was very fast. Sat thinking for a few seconds, sat up and woke her etc
What ever it could be it I don't know, but it was told under no uncertain terms to get the **** away from us and stay out of the house or i'd kill it if I ever got the chance to. Alpha man, alpha

The kettle started playing up after that, which is another story all together but it stopped and that was that.
Who know's eh.
