"Is It Hot In Here Or Am I Crazy ?"

The title of this post is a line from one of my favorite Gilbert Gottfried jokes, I cannot truly do it justice, as Gilbert speaks as only Gilbert can, but here it goes:
  "Last night I was having dinner with Charles Manson, and he turned to me and he said,"Is it hot in here, or am I crazy?"
 
  And that has nothing to do with this post, really, except that I thought it was funny, and a somewhat appropriate title for today's post.

  I was laying(lying ? I never know) in bed last night, just about ready to drop off to sleep, and this thought occurred to me" Did I lock the front door?". I was able to retrace my steps,and I was fairly confident that I had, in fact, locked the door. And this morning when I entered the living room, I saw that I had remembered correctly, and the door was locked.

  There have been other nights when I was not sure that I had locked the door, and I have gotten out of bed to go and check. I cannot remember a time that I have forgotten to lock the door overnight(I cannot swear that I have never forgotten, but I think it would stick in my head if I ever had), but that does not stop me from thinking that I have forgotten.I did recently forget to lock the door when we went to the park, but that's not quite the same thing.

   I do sort of have a point here...Is it kind of crazy that this happens to me so often? And by often, i mean maybe a couple of times a month.Does anyone else's brain work this way? And it's not just leaving the door unlocked, I occasionally have thoughts that I left the stove on, or maybe the water running.They are not all consuming, but they do flash through my brain, and sometimes linger there a few seconds.

 I do remember one time when I did leave the water running in the kitchen sink in my parents house, and I left the house. Luckily, my parents returned to the house shortly after I left, so there was no flooding or anything. So, I don't know that it means anything at all.

  So, does anyone else ever have these thoughts, or is this a sign that there's something wrong with me...Something very,very wrong with me?
