I didn't sleep well in the morning and I was in a daze. At this time, your brain will feel sensitive, so it is really in a state of trembling! There are many reasons for bed shaking, such as cars passing by, heart sticking to the bed and so on!
It is what we often say-sleep disorder. The landlord is even more like this! It's very similar to what you said, mainly caused by excessive pressure and lack of rest.
Superstition, but I said, will you consider it!
