Emotional states in dreams =/= reality.

[Daecon]

First of all, I'd like to state that this isn't any kind of request for medical advice, I'd just like to share a personal experience that I find interesting,

 

I've suffered from chronic depression and anxiety issues for several years, however I have had the same dream several times that I can remember: I'm starting University and I'm really happy and excited to be there, moving into University accommodation and starting a new life, etc.

 

While I can remember the excitement and anticipation that I feel in my dreams, I can't summon those same emotions in my waking state.

 

My question is: Is this a recognized phenomena?
