You won’t like it though.
First, get to a secluded place. A high mountaintop will do.
And by secluded, I mean no human structures nearby. Approximately two miles from any civilization. Draw a circle in chalk around you and pray to anything you can think of that it doesn’t rain.
Then cast your mind out. Up and out. Past the sun until you can see the darkness of space. Then continue. Rip through the thin shroud that is the illusion of darkness at night, and you will see that which lies beyond the stars.
When you have returned to your body, rub a tiny hole in the chalk circle and run as fast as you can. No matter what happens, you cannot look back. If you do, the madness of what is there will slowly leak into your mind.
