Me and the dancing bananas welcome you to Dreamviews!

You say that spinning "and such" don't help you prolong the dream, what else have you tried? I sometimes find spinning makes my dreams fade as well. I suggest trying rubbing your hands together if you haven't already, but the most important thing is to BELIEVE WITH ALL YOUR HEART that the dream won't fade. All doubt must be erased, it it will be for naught. Thats the best advice I can give, good luck!
