I'm Imagining a Good Time, Right?

How do we know we're having a good time? I mean, i can celebrate it. That your imagination may be accurate or not yet. But what determines whether i'm happy in this moment is that i'm imagining certain things that are true in my life,. And ican also imagine that everyone's pissed off at me. The world is just happening to me. If i don't actually do anything, if i can imagine all day long that i'm a great guitar player, but i have to actually imagine that i'm getto go. Tick.
