Answer:
Here are common reality checks that people use to lucid dream:
Mirrors. Check your reflection to see if it looks normal.
Solid objects. Push your hand against a wall or table and see if it goes through. Some people push their fingers into their opposite palm.
Hands. Look at your hands. Do they look normal?
Time. If you’re dreaming, the time on a clock will constantly change. But if you’re awake, the time will barely change.
Breathing. This popular reality check involves pinching your nose and seeing if you can breathe. If you can still breathe, you’re dreaming.
Step-by-step explanation:
Lucid dreaming techniques train your mind to notice your own consciousness. They’re also designed to help you regain or maintain consciousness as you enter REM sleep.
