The universe is hologram.

Does that mean I am not real?

Most likey if pot, alcohol, Prozac, and Thorzine are introduced enough.  How would a person be at all keen they are in reality.  Fry the brain enough in some way and even the bed seems to lack substance.  A high definition TV and especially a 3D TV plus some Pixar may also freak a person out suddenly as they can lose the sense they exist.  Then run from the TV as if they are about to have their souls ripped out.  Hope this is useful.
