Second: psychology has studied that this is just a psychological activity. Didn't there used to be a "ghost bed"? Everyone also feels that something is pressing on their bodies, and they still feel breathless when they wake up, and then they suspect that it is a "ghost pressing the bed." In fact, it's nothing, but it's easy to squeeze your heart when you sleep, causing some pressure. This phenomenon is the same as yours.
Third: "Young and dangerous people" generally believe in some gods such as Guan Gong, and feel that everything seems to have certain signs.
Fourth: People like you are generally sensitive, sensitive to danger and intuitive.
So: it is possible that this is just a dream, and there is another possibility. You may be in danger during this time. Anyway, I hope you will be careful in everything. I hope this helps you.
