Yes, absolutely. Have had many failures as well. But had enough successes and ‘misfires’ to know that is is legitimate and a powerful tool in yoir arsenal.
Last week, I saw Avatar 2, and tried to incubate a dream off it. It worked but I did not become lucid.
For the past 2 years, I have been wondering many times if my dead grandma would ever come and visit me in my dreams. She finally did a few weeks ago and it caused me to become lucid.
A few months ago I was trying to visualize and incubate camping and the details of building a fire out in the wild, before falling asleep. The dream produced was of me in a Ukrainian building with no power, trying to build a fire to keep people warm.
One of the keys that I have read about in having success with incubation is to do it in the liminal state, right before you pass out, seems to have the greatest impact there.
You can aslo reherse and acto out the scene before bed that you want to dream about, believing that you are in the dream, and becoming lucid while awake.
