Black figured man is the most common lucid dream when you feel he is choking you and you can't move.What happened to me though was a bit freakier than that.
I was waking up and could not move at all when I saw my mother taking out a glass out of my room then closing the door behind her,I got the feeling of repeatedly falling down ( can't really explain it better than that) and could move again like 10 seconds after she closed the door, went to look for my mom but she wasn't in the house,when I called her she said she had gone out 4 hours earlier...
