Staring with groggy eyes into the seemingly infinite darkness becomes much less disconcerting when your mind awakes and clears up the situation.
The window is not painted over but it is as transparent as can be. An occasional distant pinpoint of light skimming over from the left to right attests to the fact that I am moving with impressive velocity.
Do not worry because you will not become swallowed up. Instead you tear through the invisible brown paper bag of awareness so that you can see the light better.
Velocity is an illusion, but getting there is not.
