No. You don’t have superpowers. It’s not at all unusual for someone to wish they had them. But it is highly unusual to believe it. The person who told you that you turned off his lights is messing with you.
I can’t make a diagnosis on the basis of a letter. Beliefs like this can come from an organic problem, a sleep disorder, drug abuse or a mental illness. The only way to find out is to see a qualified mental health counselor who can hear your whole story.
It took courage to write to us. I understand why you emphasized that this is not a joke. You want and deserve to be taken seriously. Please follow through. Take yourself seriously. Make an appointment with a mental health counselor immediately. You deserve the relief it will give you.
I wish you well.
