Can u have hallucination of lice being in your hair?

Hallucination : Unfortunately people can have hallucinations about lice being in their hair or other bugs on their skin. When a person is very affected, this is called delusions of parasitosis or ekbom's syndrome. Here is a bit more information: http://delusion.Ucdavis.Edu/delusional.Html.

Yes: In theory, yes. What you are describing sounds very much like what is known as a tactile hallucinations. In other words, something is touching you thats not really there.
