There is a condition called "schizophrenia", what it is:
• Its a psychological disorder, makes you unsure if this is reality or just a dream.
• And of course, it can make you think your dreams and thoughts were actual events.
People with schizophrenia can change, and the effects can cause trauma in life.
Its not something funny, its serious. Just a thought, its not something to laugh at, as one of my family members has this too.
