Long lasting static :( ?

Alright so I had this plastic sheet on my bed (my regular sheet was being washed) and I didn't want to sleep on the plastic so I put my sleeping bag on there. In the morning I pulled the sleeping bag off and I saw electricity!! Blue mini-lightnings were sticking on the bag! I touched one of them and felt a little zap, but thought nothing of it. That was 3 days ago!! My hair is all static-y, and whenever I touch something or someone they get zapped. I like to think I'm getting a super power, but you know, that's ridiculous.
