Sometimes I lay thinking about things I would like to say allowed but, knowing they would be downright inappropriate, keep them to myself. Sometimes they are stressful thoughts about things I was supposed to have finished and haven't even looked at. Sometimes they are depressing thoughts that would hurt those around me. Then, sometimes they are exciting thoughts that make me giggle to myself. Seeing as this is not anonymous and I have already said I would keep these thoughts to myself, I am not telling you what they are. What I wonder is what kind of thoughts are most often guilty for keeping you awake at night?
