Have you ever had dreams and have the feeling like you are there before. Or if when you are thinking about how life exists and how the universe might be fake and you get an insane feeling like nothing is real,

The question is what other things like that have you experienced.

One more question, I remember in school a classmate said she was in a dream and felt like she was there before but she was not, the teacher called that a certain name... Do you know what its called?.

Thank you.
