If you've gotten high in real life and you know what to expect, you should be able to recreate that feeling in a lucid dream, right? I had an LD last night and in it, I came across my cousin who told me was about to go pick up a sack. If I had gone along and smoked with him, would I have experienced something similar to what I would in real life?

If all you need to do is beleive in "X" for it to happen in your dream, then getting lifted in a lucid should be plausible, right?
