I think i'm hallucinating. what can i do to make sure i'm okay?

Hallucinating: This is a serious condition. You should see a physician as soon as possible to receive medical attention. Be sure you are not taking drugs etc. That could be causing this.

See a psychiatrist!: You may or may not have a problem. But the faster you have a thorough physical and psychiatric evaluation the greater the chance that you will control the problem rather than it controlling you!
