I believe that most of our dreams are meant to be feedback to the dreamer to let the dreamer know how he/she is progressing spiritually/psychologically.

The spiral shape is probably a symbol of kundalini. The wind is a symbol of the spirit/spiritual.
The “snowy covering” probably means something like purity.
As for the trampoline, when it is upright, it can be used to jump or bounce high into the air. However, the “trampoline flipped over.” Thus, bouncing on this trampoline takes the person downward. Symbolically, this means that the dreamer would travel into the lower realms of the psyche. This is a good sign.

Hope this helps.
