well it coulds be that you can see ghost or paranormal things me I am like that 2 ppl think I am crazy when I tell them I mean my house is huanted and I dont mind it really there is a place in my yard that is 2 but dont worry about it. the time you should start worrying is if you wake up with bruses then you need to get out of your house
If you see it then it is real. I see, feel and hear what many can't. I feel sorry for them. You have an advantage. I would love to hear what you see. I see sparkly angelic entities and blueish translucent entities. Also orange ones but they don't seem too friendly yet serve their purpose. Auras and other stuff, it is limitless. You can create what you see. Try it...
You haven't really given enough information for us to answer the question. What sort of things do you see? How long does the experience last?
Everybody occasionally thinks they see something that isn't there -- fleeting illusions. It's normal. Sometimes people with a gift for visualisation may hold those illusions for a time, something like a waking dream.
There are some who actually see things that are happening in another time or place (clairvoyance) but for most of us that sort of experience is rare.
If it happens too often, or if it's something that worries you, seek professional help. A psychologist would be able to advise you better than we can.
Just remember that an illusion is when you see castles in the clouds; a delusion is when you think you're living in it.
I see things like people that are not really there. The only way I know that they are not real is because they are usually someone famous and then they are gone. Sometimes they even talk to me one time on a road trip it lasted 3 hours in the car. I asked my doctor and he said its because I have more brain activity than the average person and makes me sometimes see things that are not really there. You might have the same thing.
