You don't have to be real in VR, you just have to reach "the suspension of disbelief". That is really quite easy to do. The human mind seems to search for it.

I know in the early days of VR I had a helmet on and was walking between two buildings on a beam. Tricky bastards then made the beam (which was lying on the ground) warp so you lost your balance, I truly thought I was dying for 10 seconds.
