You enter the door. This world is a new place you can barely complehend. It contains more dimensions than makes sense. 

You feel lost and you don't know what to do. Your mind freezes and draws a blank. you pass out, and then, in the ether, as you sleep, you dream strange things that make no sense.  Vertigo sets in as you sleep. The world becomes confusing.

You are not strong enough to handle it. You die.
