Dream incubation

Dream incubation is a practiced technique of learning to "plant a seed" in the mind, in order for a specific dream topic to occur, either for recreation or to attempt to solve a problem. For example, a person might go to bed repeating to themselves that they will dream about a presentation they have coming up, or a vacation they recently took. While somewhat similar to lucid dreaming, dream incubation is simply focusing attention on a specific issue when going to sleep.
