Is "baseline" different than a "normal mood"? Or do they just call a normal mood "baseline" in people with bipolar?

I rarely feel "normal" even when I'm not hypo or depressed. I find that my "normal" feels pretty unstable actually. I've read that most people feel somewhat happy or at the very least content when in a normal mood, however I never do. I feel short bursts of hypomania or depression that quickly go away and never turn into episodes in between longer periods of what feels like a more unstable version of "normal."

Anyone else feel like this? I also rapid cycle from what I've been told, so maybe that's part of it.
