Dreaming Of The Invisible

One day I dreamed, at 2:40 am, about a window that was totally opaque, made up of black glass. After some time, the window turned totally opaque. And I now observed the outside; and what I witnessed, was literally a world bathed in visible, as well as invisible, waves of light! The outside was bathed in a combination of yellow, UV, long wave IR, as well as a slight, yet perceivable, amount of green.
