So, with that said,
I have a phobia of answering the door dirty. It's a vagueish yet looming feeling that if I answer the door remotely dirty I will never (have the opportunity to) be clean again. I don't fear other states of unpreparedness in that context. I can answer the door in a towel without batting an eye. I can go out to run errands dirty, or at least dirtier than I'd feel at ease responding to an unexpected doorbell. In a way, I know it's almost entirely baseless and ridiculous. In a way, I still said "almost".
I have a facination with cars traveling through the same intersection simultaneously. Not crashing or otherwise blocking, but moving in a syncronicity that allows everyone to go without actually stopping. Any time I'm involved in this sort of traffic movement, it leaves a sort of stamped pattern resonance in my head for many seconds after passing through. Somewhat like a mandala, but moving. Traffic on multi-lane highways merging back and forth simultaneously produces a similar feel, but not nearly as hooked into my head.
