Inception question....?

I just saw inception today and was truly blown away. Do you believe that the whole concept of "Inception" will someday become possible and real?? I believe that once humans do more reseach on the human brain and its functions, things like showing up in others dreams will be possible. But this will probably be way in the future. Anyways, the movie was brilliant yet slightly confusing. It really made you think. So what do you think? Will "inception" be possible someday?
