I had a nightmare last night that something was moving the sheets so I jumped out of bed and still it got me and was squeezing my legs all the way up and I thought I opened my eyes and I was in bed but couldn't move except for my head so I screamed to wake myself up and it worked but I still gad the sensation of my legs being squeezed.
It was a stressful day so I guess that's why I had the nightmare.
