I have had a similar situation, but I always feel that I am not dreaming.
At that time, I felt a little empty and very tired, and then I lay flat on the bed and rested. When I was half asleep, I felt a powerful force dragging me from the head of the bed to the end of the bed. I want to shout, but I can't move at all. I can't shout. I suddenly woke up and people slowly recovered, only to find that I was still lying in the same place, not moving at all.
This has only happened once. I don't believe in ghosts in my heart, although I live in an environment with a particularly strong ghost culture. I also like watching ghost movies.
Perhaps because of this, I especially believe in cause and effect. I have never done anything to hurt anyone in my life. Why are there grievances or ghosts around me? So I prefer to be particularly weak.
At the same time, I also remind you that you must adjust your diet and sleep and take good care of your health.
