I am autistic, there are some things I do which I'm wondering if they are normal or just an autistic thing. For example, I have a few fluffy toys which I take to bed, I buy myself some fidget toys and similar things, I somerimes make odd noises if I'm excited or clentch my teeth together and squeel, I bite my duvet and squeel at the same time if I go in my bedroom as I like the feel and smell of it. Are these "normal" behaviours?
