I am not sure how many jobs/gigs you have had but to those of us who move from contract to job to contract etc have a ramp up path at the beginning of a new gig. I personally find I really dont have a full handle on it until I start dreaming about the job. The subconcious mind working in its way to assimilate the info needed for the gig. The nakedness in public with unknown requirements could also just be anxiety about the waking state. How many times have each of us been suprised that an icon of thought once met, is dumber than a rock? This makes us nervous on how We are perceived.
Greg's shortness of breath made me think of the connection between seal state (see SIDS and Seals) and a dream that would kick him into wakefulness.
Extremely violent dreams often mean you arnt getting enough sex. ( insert your personal definition of enough here)
The dream state is important to the waking state whether precog (assembling random waking events into a coherent meaning) or as a rest from sanity. Being sane all the time will result in insanity.
