Vortexes and Wormholes

Vortexes. Tornadoes. There is something very powerful about creating these in the Dream Dimension.

It's interesting that my first lucid dream task I completed on DV was creating tornadoes.

I do not fully understand this phenomenon, but I do know that they lead to portals when horizontal, usually.

Tornadoes moving over the ground have the ability to trap enemies within them. I surmise that creating a tornado around yourself will create a barrier.

Wormholes

Wormholes are tubes that link dimensions. We go through these whenever we go through a portal, a mirror, a door into another world. Often we are in the wormhole for such a short time we don't even realize its existence.
The rabbit hole Alice went through was a wormhole.
The birth canal is a physical wormhole. You go from one world of darkness, warmth, and weightlessness, to one of greatly varying physical stimuli.
