As a kid I watched a lot of Star Trek: The Next Generation. Recently I've been watching some of the episodes on time and reality again, and some are really well writen and have stuck with me since the first time I saw them. One of them reminded me of a subject that's tied into a lot of the Buddhist thought I've studied: it's an episode called "Ship in a Bottle," and almost all of it takes place on a holodeck, a large, empty room in which a holographic world is created and people use for recreation.
The basic storyline is that a holographic character is designed to be very advanced and actually gains consciousness and self-awareness. This character gains access to the holodeck controls and creates the entire ship as a holographic program so that he can trick Captain Picard into giving him his authorization which gives him control of the real ship. In the end, Picard and two other crewmates realize what is going on (they have been on the holodeck the whole time), create another holographic representation of the ship, and the holo-character is stored in a chip still under the impression that he was able to cross over to the real world (yeah I know it's complicated in text). The program is set to run indefinitely in the chip.
When Picard tells the others about what happened, he has a great line:
"For all we know, this might just be an elaborate simulation running inside a little device sitting on someone's table."
All but Lt. Barclay leave the room. He says "computer, end program!" but nothing happens.
The point is, it's easy for us to think this world is "real," and we live according to this assumption and thereby limit ourselves and suffer; we are trapped in a web of meaning we have created ourselves. But it is all illusory - the meaning we project exists only conventionally. It's like thinking that a dream is real while it is happening - and don't most people do this? React to things as if they have inherent existence, or are not lucid as we might call it?
Here's a video I just found on the subject:

If anybody knows of a better video on this, please mention it - i just looked for something called "holographic universe" and posted it here for a reference.
