I was thinking if wormholes for interstellar travel and blackholes no light can escape...well there's the shape of a body at the end of that wormhole from which no life can escape and besides "Brainstorm" is one of my favorite movies,that and "Dreamscape". I especially like the part when D Quaid goes into the dream and you see the vortex going round hearing the screams in the background. "Altered States" after he drinks the stuff and the soup swirls and flares like electric shocks. "Brainstorm" when hes fighting the physical effects to get to the end of the tunnel. I love sci fi.
