this might sound weird but just for jokes.......

if ur sizo and ur dreaming could ur spilt perosnaitly apear in the dream some where

hmm i think it could. but the question is which one will you be at the time? and because both of them is really you will you be both at the same time? or neiter and be in 3rd person? I wonder wut it would be lik, controlin and being both of you at the same time in a dream if thats wut would happen.

Actually dreams work on perception of reality.
You could bring to life a monster and have it attack someone I have found.
This is just more taxing on your awareness.
