A chemical method of inducing them.

When I was younger, I rarely dreamt, period. (And yes, I get the bullshit that I was dreaming but I just didn’t know it. Sorry, if I don’t actually have any memory of experiencing it, it’s not dreaming — it’s just some weird and useless unrememorable mental state ).

But in my elder years, I dream quite a bit, and most of it is unpleasant (sort of a nightmare, in which things are continuously shifting, and where I am and what I have, or what I possess, or how I am being transported is inconstant).

But I have also started, on rare occasions, to have lucid dreams. I particularly remember one in which the cat started talking to me (in English), and I realized, “Gee, I’m pretty sure cats don’t do that. I must be dreaming.” And the dream was amazingly realistic, just like real life, so it was pretty cool. I’m not sure it’s useful, but it’s a lot better than the crap dreams I was having in which I didn’t understand that I was dreaming, until I finally realized (because everything was continually changing) that it was a dream, but at that point, I woke up.
