I don't know about the dreams. But, this sure made me sleepy for a number of days before I got used to taking it. I even started to fall asleep while standing up to try and stay awake. For this reason I think this medication is somewhat dangerous. Valium is also a muscle relaxer and was used before this type of medication came on the market. The 2 mg dose that you took never had the effect of causing so much drowsiness.
