Unique Sense

I have posted about sense's, as they relate to autism, before. The sensory experience seems to be unique for autistic individuals. I work with an individual who likes to dance! It almost seems like he has the music in him. He is deaf and mute but somehow he likes to dance. I do not completely comprehend it but I think it he learned this through viewing other people dance. How is this sensory? This is sensory because he dances when he feels grass underneath him. When he feels grass in parks, he starts dancing. He sense's the grass touching him and he seems to enjoy it. Please feed your autistic individuals sensory diet.
