I don't know if this is the right section but has anyone here been able to manipulate the dream world during sleep paralysis?

Once i was lying in bed, and i suddenly fell into sleep paralysis. So i decided i would try and do a little experiment. I wanted to see if i could make a person pop out of nowhere. So visualized and as long as i held my concentration a person came out of nowhere but they kept on popping back into nothingness and then back into existence. That person was on my bed and kept on thrashing around violently and then when i let my concentration go all together disappeared completely.
