Last night's dream involved a certain good feeling that I rarely experience, especially in dreams.
I was riding a bicycle (I never do in real life) in a forest that seemed to be, according to the environment, somewhere other than my home country. I was riding alone and I was speeding in an upgoing slope without getting tired. This is when I got that good feeling. It was a feeling of invincibility. I was able to quickly climb very steep slopes without feeling short of breath and without feeling any pain in my muscles. I cannot remember any other details about this dream and I probably shouldn't try to remember too hard or otherwise I will end up making shit up.
It was enjoyable and motivating. When I woke up (probably during or in the end of that dream) I was in the correct state of mind for physical activity.
