Has anyone noticed a correlation between going to bed exhausted and having poor dream recall the next day? I started a new workout program about 10 days ago and have noticed a significant decrease in my dream recall. Up until I started this workout program, I was able to remember at least one dream a night and often 2 or 3. But, in the past week, I've only remembered one.

Before I started this workout program, I'd usually go to bed around 12 - 1am. I started to wonder about the link between exhaustion and recall last night as I was fighting to stay awake past 10:30pm. Any thoughts on this?
