Am I Going Nuts?

It's a crazy story, but it is true.  

Last night (Friday night), I was super tired and went to bed relatively early (for me).  However, I was constantly awakened by a child who would not stay in bed and sleep (not Caleb, but Abby).  After being awakened the third time, I ended up moving to the couch.  

That didn't help either.  Between the thunder and noises I kept hearing, I just couldn't fall asleep. 

I finally fell asleep for a bit, but woke up again to who knows what.  What was that sound?

I thought perhaps it was the ice maker, so I lay there listening, but I didn't hear it.  Then I heard what sounded like ice falling from the ice machine onto the floor. I just left it.  I didn't care.  

As I was falling back asleep, I hear noises again, but thought perhaps it was my instant pot cooling after I turned it off. (I had yogurt in it and removed it)  Just as I started to fall asleep again, I heard that noise like an ice cube falling.  I got up and looked in the kitchen.  I checked the floor and looked at the ice maker.  Nothing was off and there was not a single wet spot or ice cube on the floor. 

I started to look around and noticed two hickory nuts on the floor in the kitchen.  I instantly looked at the ceiling as if I had a squirrel tossing nuts from above.  I even looked in the lazy susan were I used to keep a bowl of hickory nuts.  That's when I got Al out of bed (he had just returned to bed after coming out for a drink). He obviously had already fallen asleep because he startled, but came out.  

We both looked around and were quite confused as to how two hickory nuts would fall.  We considered that someone had left them on the counter and the vibrations from the thunder storm shook them to the floor.  We both went back to sleep, he, to the bed, I, to the couch.  At this point, my posture headache was coming on.  I couldn't shut my brain off as I pondered what in the world was going on and where the nuts had fallen from.  (Believe me, when tired, your brain can think some crazy things.) 

Just as I was falling asleep, I heard what sounded like two nuts falling from somewhere, but near Caleb's room.  I got up and looked, but saw nothing.  I heard nothing after that either.  

In the morning, I slept a lot later than usual.  (8 o'clock rather than 6 o'clock).  Caleb was standing behind me on the couch.  I asked him if he had any hickory nuts in his room.  

He answered yes.  I asked him where he got them and he said he had them for a while "like back in February or March".  He told me he had "like five", yet when I asked him to bring them to me, he only brought two.  I asked him if he was awake in the middle of the night throwing hickory nuts.  He said he wasn't. 

I am baffled.  I am sure it was him, but what in the world?  How can one be sleep walking and "throwing" that long? And how could he be moving around so much without me hearing him?  

Later in the day, he thought it quite funny and acted like he had been throwing nuts.  I on the other had wonder...and wonder.
