Which itself was a total ripoff of the Star Trek: The Next Generation episode "The Inner Light".

I haven't seen either the Star Trek or 4400 episode (I hadn't even heard of 4400 until just now) but the concept sounds very much like both Ambrose Bierce's "An Occurrence At Owl Creek Bridge" (1890) and Borges's "The Secret Miracle" (1944). Perhaps both programmes just ripped it off from one of those?
