I’ve honestly never considered before whether it could be like something to be a character in my dream - if it’s part of the same consciousness. Doesn’t seem obvious that it couldn’t be.
And my personal view is that the answer is definitely no. There’s no dreamer. The dream is appearing in the consciousness of a biological being with my genes, history, and memories that’s currently in a state of sleep.
This comes with other ramifications too. There’s no decision-maker either.
Use a pin code or a pattern. If you’re concerned about privacy, then handing tech companies your fingerprint isn’t very wise to begin with.
