First off- this is in the opiates section because weird dreams are a known side effect of any opioid. My friend happened to be taking tramadol when this occured. My friend was taking tram every day for a while, around 700 mg a day. On one occasion he stopped getting them on the weekend as to save his supply for fun times in school. The first weekend this happened, (he took his last pills friday morning), he had crazy messed up dreams the next night. This was expected as it has happened to him before on a smaller scale. This night was exceptionally bad, however, as the dreams he experienced were so bad and so confusing and traumatizing that he lost a sense of reality the next morning. Everything seemed to be scary and new, events and objects that once had sentimental value to him now seemed dark and twisted, with a sense of hopelessness. He is an athlete, and he all of a sudden had no desire to go out and play basketball on that beautiful day. The anatomy of the human body seemed weird and confusing as he looked in the mirror and at his limbs and hands. He was absolutely a scared shell of a human being for no apparent reason. All he could really think about was the dream, and when that memory faded the bad feelings seemed to go on. It was not positive energy at all, but it was not negative energy either. It was a loss of energy itself and existence meant nothing for about two weeks. He was soooo happy to finally be back to his old self, but he still has questions about what happened during that time span. Does anyone know why opiates cause weird dreams sometimes? Has anyone had a similar experience? He is filled to the brim with positive energy now as he will never touch tramadol again (withdrawl, but thats a story for another time) but he would like to get any and all information about what he has experienced.
