Important: what is LDing used for? (e.g. conquering fears)

I’m planning to give a very short lesson on a subject of my choice at college, and I want to make it on LDing.

It’s in a small group, so I hope I won’t run into too many difficulties, but I expect to have some “what is that good for” questions.

So, examples of benefits (the more detailed the better!) would be very helpful.

Thanks in advance!

Lucid dreaming is used for a multitied of reasons. At mere convenience, I’ll give you a link…

And if that helped at all, you’re very much welcome.
