Background: Pure OCD, Anxiety, Depression etc. Not related to this post.

Long story short. Every time I have a cold, especially when related to the sinuses, I get into an almost euphoric state of mind. With almost exclusively positive memories, music sounds better, I get more creative and things smell better (everything smells the same but better). I feel like I become the normal me and it feels great.

Ideally I would like to stay in this state of mind but it goes away once the cold or sinus infection has passed. No one that I have talked to has heard of anyone with a similar "condition".

Any thoughts?
