That's your MINIATURE SUPER TELESCOPE! It's a scale model of the COLLAPSIBLE SUPER TELESCOPE you developed however long ago. Unfortunately its diminished size makes it a lot less effective, and you can only see faint outlines of faraway WINDOW UNITS. Also you have to shimmy your way up the electrical cord and it's this whole big ordeal.
When you were big, you used to keep tabs on someone you once thought of as your friend. But now you know that she wasn't actually real. None of this is. The fact that your nightmares are now carrying her face makes you think you might be slipping even closer to the brink of insanity, but you have to stay strong.
