I make up scenarios in my head of everything and anything. Conversations, future events, past events, world events. Anything
Along the lines of
*walks along the river,*
imagines: sees someone who has fallen in, wonders if I am able to throw the lifebuoy far enough to reach the person, and if not, if I should jump in, and if I do, if I am a strong enough swimmer. Then image a scenario where I need to be saved too and another where I save the person
yeah, I'm weird
