I work from 8pm - 8am. I have to attempt to "flip" my schedule on my days off if I ever want to get anything accomplished. Needless to say, this wreaks havoc on my sleep schedule. This seems to make my recall a bit harder than it used to be (earlier in my life)

Work days, I sleep from 9, 10, or 11am - 4, 5 or 6pm.
Off days I sleep anywhere between midnight and 9am.

Anyone else have to do this? Just curious how your dreams are affected if you deal with a similar schedule.
