Hearing things

Hi everyone
I've got an extensive psych history of depression and anxiety and am on five psych meds. I spent the last couple of days in hospital for a bleeding cyst and they gave me morphine, paracetamol (sp?) drips and an anti-inflammatory until the pain lessened. As I got home today I could hear what sounded like bells, or like accordion music - the same tones as the bells in the hospital. It was really bugging me and I realised that there wasn't actually anything playing out loud. I've had this previously at a workplace where there were lots of phones and I "thought" I could always hear the phones ringing, but I guess there it felt like there could conceivably always be a phone ringing. This phantom music has been bugging me on and off the whole day. I feel really stupid trying to tell my psychologist or psychiatrist stuff like this. Part of me worries that this, as well as other little things like it, is going to escalate, and another part of me rationalises that it will never escalate, because I'm totally aware that it's not real, so how could it be a problem?
Trigger warning?
I used to abuse sleeping pills a lot and would hallucinate a lot on them, and stuff similar to that sometimes happens, but it almost feels like I can control it. While I'm looking at things it can look like they're moving as though they're breathing. I'm always seeing little things in the corners of my vision and turn to look but there isn't anything. Logically, I know if a friend told this to me I would easily tell them to tell their dr. I just have this idiot in me saying: shut up moron, why would you tell your dr?

I encourage you to tell your doctor. Best wishes.

Morphine can cause all kinds of delusions in people. Even in those who have no psych issues. I would tell your doctor, but it's probably not naything to worry about.
