OK, I want to ask "Is it possible?" but almost anything is possible.

The better question is, how likely is it, with 'training'?

There are two things I would really like to do occasionally in my dreams. One is to go through REAL experiences I have had in the past that are no longer fully possible in the real world.

I am a big theme park fan, and I would love to be able to re-experience rides (and even whole parks) that have been closed since the last time I was on them. Now understand, there have been times that I have ridden things that my dream 'claims' were these rides or places, but they weren't really even close. But with training, can you get your mind to let you live back through early memories that you have consciously more or less forgotten?

Secondly, there are two or three dreams that I have had in the past that were cool enough that I would really love to dream the same dream again, some time. Has anybody ever convinced their mind to give them an old dream back again, years or decades later? Again, I'm not looking for just something vaguely close ... I do that all the time. I mean having the same exact (or extremely close) dream again, because you want to.

No harm in asking ...
