Im not sure about ur "back into the future" question but I wanted to address your question about Inception. I don't know exactly what you meant by "could it do something as real as Inception?" but if you're asking if your dreams could feel as real as they were in Inception then the answere is most definitley YES! I have had many dreams that looked, smelled, sounded, and felt every bit as real as reality. Many people here will tell you they have the same experiences in the dream world.
