What is it like to feel the bed shaking?

Hello, I feel the bed shaking when I sleep. Considering the nerve compression, it has something to do with it. It's caused by my heartbeat. If I feel shivering in bed, I will relax myself, stretch my legs and think of something else to divert my attention. It will get better gradually. I feel the same way. The first principle of distraction is to go to the hospital if it is still not good.
