I ask a dream character what their favourite memory is.
This is an intriguing one. Once I asked what their earliest memory was, and got funny and interesting results. One random lady on the sidewalk said it had something to do with us sitting in a wood fishing boat(she didn't say that, it was the image that popped up when she was recounting her memory) . I was reading a book or something and I think someone fell out. It was just so strange and random.
Switch perspectives with a dream character.
I ask a dream character to solve a simple maths problem on paper (2+3 =?)
I summon a childhood friend (predetermined) and ask them what they think of who I've become.
