I found it used to disrupt my ability to fall asleep, and I didn't dream, or at least didn't remember doing so. It also impacted my memory when awake, which makes sense if it was messing with my sleep cycles.
However, I was able to fix all of those problems by consistently ceasing use 4 hours prior to going to sleep.
