Questions raised during the process of packing up my apartment and moving to a new apartment

Where did this Yoga matt come from?
How long am I supposed to keep this shrink-wrapped cd that came with my laptop three years ago? Forever?
When did my third desk drawer become a black hole of tax forms smudged with pizza fingerprints?
How majestic—I just found a pellet-like marshmallow in my hair.
Since when did I own this heavy marble pen?
Why am I suddenly wearing a piano key tie?
Why are there raisins in tuxedos playing the saxophone behind me?
Why am I sashaying down this glowing staircase?
Why am I clenching a rose in my teeth and sitting down at the piano to play a jazzy duet with a dapper cat?
Why am I turning over this huge hourglass so I can do it all over again?
