Is it normal that i have started to think in punctuation marks ?

For the last 2 months my internal dialogue has been punctuating my thoughts, like a normal stream of consiousness might be "Oh look a dog I wonder what breed it is it looks so soft I wonder if the owner will let me pet it?" Whereas I would think "oh comma look a dog full-stop I wonder what breed it is comma it looks so soft full-stop I wonder if the owner would let me pet it". It's not really something I'm properly worried about but it does get on my nerves because I will go back over the sentance I just said in my head and go through it 2,3 or 4 times to correct the punctuation (not all the time but around half). As I said it's not urgent at all but I thought id share it on here to see if anyone else has done this before -thanks.
