Are there any limitations to a dream?
If you met someone in a dream who insisted they were real, what would you say to them?
If you met an entire world full of people in a dream who insisted they were real, what would you say to them?
If this was a dream, would you be real or just part of the dream?
Would the idea of someone being the dreamer also be a dream?
Can you prove for an absolute fact that this isn't a very consistent 80+ year long dream?
If this is a dream, what is death?
If you were suicidal, but every time you "died" you came back to your body, how many attempts would you make before you admitted something weird was going on? (For me it was 3)
How many "out of body" (or "looking inside") experiences would you need to go through before you realized being inside a human body was entirely optional?
Do other people have any inherent existence?
