Reality - I think, but am I?

I think.

And I think that I am.

But am I really?

Or am I just in the mirror, looking back?

Or am I a character in someones else's dream?

Or am I in a play, believing that the play's the thing?

And if the play's not the thing, then what is?


Robert Heinlein wrote a story, once, in which a man invented a machine that could measure the span of a person's life. When viewed in the context of time, people did not appear as they normally do, but appeared as long, worm-like things that began at their birth and ended at their death.

What do we appear as when viewed from other dimensions? If we have a current existence that extends past the reality that we know, does all that we are or were or will be form just a projection from a greater entity? A lobe that extends into what we view as reality?

If so, which is the reality? Is it what we normally perceive, or does it include all that underlies it? How is reality defined? If reality is what is real, is the underlying reality real in that sense? Or would it be not real, but still exist?
