It would be interesting if you could play the "false awakening" game.

you think you've woken up only to discover you're still dreaming.

The 2nd time this happens you smile.

When it happens 3 times in a row, you start doing everything you can possibly think of to see if you can tell whether you're awake or dreaming.

When it happens the 4th or 5th time, and you've exhausted all of your "reality checks," you realize you have absolutely no objective way to determine if you're awake or dreaming.

Then what is this?
