Imagination

I've wondered a lot lately about imagination. What is it, and why do so many people seem to think autistic people are all deficient in it? T-- seems just fine in this department. After dumping water on the floor, he pointed at the spill and said: "It's the sun!" then after we threw a towel over it, he promptly sat on it and said: "T---'s having a picnic on the grass!" I think imagination is just scrambled up memories. I think the Eides said that all of our thoughts are just memories. I think they're right.
