Why do you always dream at three or four o'clock recently? Your dream is still very scary. Things like paranormal things happen to you, and you always dream about your old primary school. ...

People usually fall asleep in 1-2 hours, then go into deep sleep and really start dreaming, so it is normal for you to wake up at three or four o'clock. You may be in a bad mood recently and very sensitive to external things, so some unimportant details in your life will be brought into your dreams. Besides, your sleeping environment may be a little bad. It's sultry and humid recently, so I suggest you bask in bask in the quilt. Soft and dry bedding and quilt cover are helpful.
