Yes. When I'm just falling asleep but still semi-conscious. The better my Wellbutrin is working, the more often if happens. Sometimes it's more than one voice. Sometimes it switches from male to female. Dopaminergic drugs are tied to auditory hallucinations, so it makes sense that Wellbutrin could cause that. I also have dreams that are weird but the content isn't scary, yet they'll wake me up with this scared feeling and sometimes I'll have to roll over and make sure noone is standing behind me, even though rationally I know that's ridiculous. I'll just have a real uneasy feeling nonetheless.
It's a pain in the ass sometimes, but I know what's real and what's not and after REM sleep I usually am just fine.
