Dramamine is a medication used for motion sickness manufactured by Pfizer. It is available OTC (over the counter), without a prescription in many areas. The drug it contains is called dimenhydrinate, a close chemical cousin to diphenhydramine HCl.
Dramamine is also the name of a song by Modest Mouse.
Dramamine is also available in the form of Gravol in Canada and other countries.
Taking Dramamine II (meclizine HCl) may help; it was developed to reduce the sleep-inducing effects of Dramamine.
The most common hallucinations of Dramamine are auditory; you frequently hear voices, sounds, and sometimes your name being called by an unknown person/thing.
