[A sigh. Here we go.]

Sometimes...the forces or beings that bring us to those other worlds...take our memories away when we're brought back home. Donnie and I have both gone home...with no memories of the world we were in...and when we were brought back, our memories returned.

When we're taken from home...time is also...paused...for the time we're gone....and it starts up when we return...that's why you never noticed when he left...because time was suspended while he was gone...
