I have actually heard this before with some antihistamines and with hydroxyzine. It tends to cause vivid dreams and for some people it induces nightmares. This effect usually stops after time on a the drug (anywhere from a few days to a few weeks). Sometimes I think since it causes drowsiness and it puts people into REM sleep where we dream, this is why it occurs. It may help you to avoid watching certain TV shows or avoid reading certain books before sleep. Opt for comedies or pleasant reading material rather than high action drama etc.
