I am not the kind to regularly have nightmares, but in the past 3 or so weeks I have had lots of vivid, terrifying dreams. The dreams are all over the map as far as circumstances and characters involved, but they have all been extremely upsetting. Several times I have been unable to go back to sleep because a dream unsettled me so completely.
I have no idea why this is happening, or even if it is 100% tied to my new running routine. I do run late evenings many times, which might make going to bed at 10 PM difficult for my body. I wonder if this is a common complaint for people who begin exercising regularly or if I am just plain strange.
