Asked my boy what he see's when he closes his eyes... His reply..Sometimes Aliens!!

So I was putting my boy to bed last night and I asked him if he see's anything when he closes his eyes. He says, sometimes he can see colors and round circles of colors that descend away from him. He also said that sometimes he can look at a person's eyes, then close his and see two round colored circles with dots in the middle. He then says, he also see's circles with no dots which he identifies as aliens. I aked him if he has seen any aliens without the dots who he might know. He says one girl in his class has no dots in the circles that he sees. Then, he says " Dad you'll be happy to know that you are not an alien"...LOL.. I found that quite comical...
