I dont want to test methods I feel uncomfortable with, but if I get an LD Ill create a wormhole, and the day I succeeded Ill post the result here.
When I had a LD last night, I planned on doing this when I gained full control to teleport, but I lost lucidity quickly 
Has any one tried running like a cheetah to get anywhere fast?
I like the idea of the…portable portal…it’d be cool for other stuff too…like moving large objects…or even pull “needed” items out like Felix’s magic bag…
That hole thing sounds like an amazing idea, I will definitely give it a go in my next LD
