I read your other post about the subconscious mind.

I would stay at the library all day and would realize I had read only two pages at the end of the day when am about to go home. Restlessness was my brother. I would think of all the things I could do to while away time when am not in the library or in class and when I do not find anything to while away time at I would just stare blankly at thin air until it is time to go home.

This is what you should do before going to bed but you were doing it at the wrong time and used the conscious mind incorrectly. It is call "day dreaming" for a good reason.

Write them down for before the bed time and delegate to the subconscious mind.

Make a list for your conscious mind to focus on.

All the best!
