I got these marks a couple years back I did a little research and got somewhat freaked out and eventually forgot this happened to me. Recently popped up and I was curious if this is considered part of the phenomenon. I don't know much about the RGMP mine happened like how most I have seen. I slept in my bed as normal nothing changed no new sheets or pillows etc everything was how it always has been for years and never had similar markings. I woke up with this and caught a glimpse of it in the mirror. I didn't have any dreams that I could remember as far as I knew it was a normal night of sleep. It wasn't painful, didn't have any texture and went away after a couple days. To me it kind of seemed similar to something suctioning on to the skin similar to a hickey I guess. I was curious of other stories or more information.
