In this past week I've heard two different things. I heard my mom say my name as I was heading into the bathroom and I turned around and no one was there. Then a couple nights ago I heard my dad yelling but I knew he was in bed sleeping.

There are multiple reasons why this could happen, and I need to know if this is something I should tell the doctor.

1. I've heard things on lithium and zyprexa before, but not for months.
2. I've started wellbutrin a month ago, and anti-depressants caused my manic episode, but so far I have not experienced any negative side effects.
3. I've smoked weed within a day or two of hearing things.
4. I've drunk 2-4 glasses of wine a few times the past week and a half.
5. I just started my second week of college and have been very stressed out.

I guess what I'm really wondering is, is this bipolar-related, stress-related, or substance-related, or a combination of things, and should I tell the doctor?
