Hasta La Motion!

I guess similar to some supernatural movies where someone floats above their bed, is there a way to do this outside (without wires and a crane?)

I have access to a great green screen studio on campus. And the shot doesn’t have to be a long one. I guess one way is to have them lie down and mask the object theyre lying on, then after effects them to look like theyre floating. It’s just the close ups / medium shots of them lifting up and floating down is harder to shoot.

We just want to make it look like one of the characters calls the other, and floats them over (in an outside, wooded setting.) If you could help me out, I’d truly appreciate it.
