Not really the same. Some dreams, the more vivid kind can have smells or feelings. Like the one I had yesterday in which I had cat ears, whiskers, and a tail, and also curiously enough, horns as well. I could run my finger along them and feel the texture in them as well as the warmth in the horns. It was weird.

AI doesn’t have smells, feeling, or textures, or if it did it can’t really give it to you. Only sights and sounds. So they aren’t really the same. Dreams can come in all 5 senses, AI can only channel through 2. Usually just 1.
