This is not a psychological disorder, but there are some separation problems when you are not awake. Many people will have such problems, and you don't have to worry about this situation at all. This may be caused by your lack of rest and energy exhaustion, so you should have a good rest, do more aerobic exercise and reduce mental consumption during this time. If you find that other behaviors are inconsistent with your thinking, you need psychotherapy.
