The Aliens know you are looking for them. Your anxiety over being watched is what is making them watch you. The Aliens are everywhere. You can see patterns. That conspiracy was built for you, and those like you who are peering into the darkness expecting to see something. You completely asked for it. You got a return on your Investment. You gave anxiety about little green men to the Universe, so the Universe throws little green men at you. It's not a delusion. Stop egging them on. Let it go.
