Too much thinking

I felt very tired at about 12.30pm, so I went for a nap. I didn't get up until 4.45pm, but had laid there awake for a couple of hours. I watched a sunny day change into nightfall. I felt too tired to move, even though my joints are aching. My mind was running in full throttle, and I became aware that my foot was tapping vigorously.
The kaleidoscope above represents what has been happening in my head. Thoughts come into your head and most are forgotten almost as soon as they were born. There is a constant deluge of  thoughts and images. You sense real things and people, but in the wrong context, which I do find unsettling. The whole thing is very fluid and abstract, and quite exhausting.
I have nothing else to tell you. I just wanted to catch the moment while it was fresh.
