Quote from: Alana Ashleigh on Yesterday at 10:01:16 PMMy work schedule has been very wonky the last few weeks. I should be go back a straight shift in a few days. That is definitely playing a part in this, I suspect. It's interesting you mention sleep. I've been having very intense dreams lately.
I think you might be onto something there. REM sleep is when your mind processes all of the stuff it has observed and stored in short-term memory. If something happens (good or bad) that stirs a strong emotional response, that memory will be stronger than something like remembering that you walked into a room.
During REM, the mind sorts through these memories, much like sorting your mail. The important stuff gets moved into long-term memory, and the "junk mail" gets moved to the "discard pile". Memories that are stored in the brain require energy to maintain them, just like a computer. This sorting process allows the mind to be more efficient by not wasting energy on unimportant things.
What happens to the "discard pile"? A way to think of it is like this. It required energy to store those memories in the first place, so the mind needs a way to recover that energy. Since the memories are a collection of data received from the senses, the energy recovery process is the same thing in reverse, out through the senses. We experience this process as dreams.
The subject matter of the dream is not important because it is just "junk mail" being purged from the system. It is not something to worry about. Powerful dreams are a sign that powerful stuff is being purged and that energy is being reclaimed. The problems arise when REM sleep is interrupted so that the mind can't clear out the clutter. If the dreams are too powerful or too disruptive, they can cause you to wake up before the work was done. Over time, this can leave you feeling fatigued, overwhelmed, anxious, or stressed. This is a common problem with shift workers.
My dad worked rotating shifts when he worked for NASA. When he worked Days or Graveyard, he was ok. But when he worked Swing Shift, he had a rough time of it. Working on four hours, off four hours, then back on four hours, makes it hard to adjust to. Then just when you've about had it covered, your shift changes to something else.
Hopefully, this will get resolved when you get back to straight shifts.
