Haha it definitely can help spark some interesting brainwaves. I recommend it!
But even more than that, tell yourself "I will have a dream tonight" and when you do after a few days of doing that, immediately write down anything you can remember in a dream journal. After doing this just a few times, you will blast off. Before you know it, you will have 3-4 vivid dreams a night! It can get too intense even if you do it long enough.

I will try it... And let you know in few days :)

Please do! Can't wait to hear how it goes!
