I have been taking Citalopram (Celexa in US) for about three weeks now and every night for the past two weeks Ive had a vivid dream or a nightmare. I quite often have dreams but not this frequent or clear. They dont bother me all that much, infact I find them quite interesting, however Im simply intrigued as to what may be causing this! I also was taking Zopiclone (Lunesta in the USA) every so often for about three weeks to help my insomnia, but dont think it could still have this effect on me after two weeks of not taking it.
