I’ve noticed that I get more dreams, and more vivid dreams on days where I do intensity (including SS). In contrast, I tend to dream very little, or, at least, don’t remember my dreams on days where all I do is zone 2.
This could be in my head, completely by chance, or a mix of factors, but I’m curious to see if anyone else has experienced anything similar. This might be a good topic to explore. I wonder how it affects recovery.
