In the last two days I’ve had dreams about:
Defecating in a plastic bag at my father’s house
Being at Burning Man but needing to get to the Reno airport to fly to Seattle;
A dingy
Downloading a U2 album (which I then woke up and did)

I think of dreams as the way your brain’s file clerk passes the time as it stores away your memories. My internal file clerk is cearly very bored with her job.
