Where do new ideas come from?

I think that new ideas come from your imagination. Just any imagination that pops in your head can make a brand new idea. I think that ideas can come from a lot of different places. From friends, the past, your life, books, movies, it is just everything. Everything is an idea. When you let your mind wonder a new idea will pop up. WHen you think about the past a new idea will pop up. So in general I think ideas can come from any where you imagine it to be from, and you can get new ideas any time, even when you don't expect one.
