Often dream of being bitten by a hand and struggling desperately?

Hello, this friend, don't worry too much and be nervous. Generally speaking, dreams have little to do with our real life. It may be caused by your recent emotional tension, or it may be caused by your sleeping posture. Does pressing the arm cause poor blood flow? After all, the brain forms a kind of consciousness. In fact, the brain is reminding you that you can change your posture to keep the blood flowing.
