The music that comes to mind here for me is Kool & the Gang's "Celebration!" Will definitely try this as the "I'm dreaming" mantra is not working for my WILDs, and visualizing scenes inevitably keeps me awake.
p.s. interesting that a good friend of mine has reported over a hundred of WILDs using the "swing" technique: imagine swinging on a park swing, eventually he'd appear in the park and then go off and do LD stuff. I tried that but I find imagining swinging makes me move my physical eyes keeping me awake. I've also been swimming all my life so I'll try the swimming motions. I've been wanting to LD at a water park (heh heh!) so this could be a great way to get there!
