The blog block

So i had something really interesting to write about all day. I had been thinking it over from all perspectives and I could not wait to grace myself with typing it out. Unfortunately it was wiped from my memory by a ridiculous question. Before hall gov officially began we were just sitting around chatting as usual when someone asked, "What do blind people dream about?" I could think of nothing else, my blog topic was lost. Can they dream of tangible objects? can they see in their minds? Do people really know what anything looks like until they see it? It is said that everything in a dream plays off what we have seen. That does not explain monsters children see, during nightmares. I can make up many make believe objects and organisms in my mind, that to my knowledge I have never seen. Are even these make believe images based of shapes and structures that I have already seen. It is not really an unanswerable question except for at the moment because I do not know any blind people to ask. However, this question made me think deeper and now I wonder if fetuses in late stage have dreams? I do not see why they would not have thoughts late in a pregnancy assuming newborns think, which I believe they do. They must be simple thoughts but I am sure they exists. I just wonder if fetuses know whats going down as they are living in the womb, or if they are freaking out the whole time.
