I just had an Idea About summoning people.

I havent tried it yet, but i figured it might work.
In a dream, Sit down at a PC/open your "Lucid Menu" And hit CTRL+F (wich is the find function in internet explorer) And type in the name of the person you want to find. You could make them appear in a pop up and drag them out or something.
Not the best idea ever, but i just had to share it somewhere :p

Thats a great idea, if you like to have modern dreams.

There is no such thing as a bad idea, since if they work then they are all equal.
