Here's my answer - I would not have wings, I would just fly. No wings, no wacky flying machine, just me. Ofcourse to do this, I must achieve lucidity . The basic premise of Lucid Dreaming is being conscious while you're dreaming, thus you are free from the physical world. If you were to read alt.dreams.lucid , you'd know that one of the best things to do when you're lucid is fly.
Some dreams describe foreign worlds and never-ever lands and are really beautiful.
This happens when your mind is the only limit. Those who know me, know my fascination with the Pitcairn Islands. Ever since I first saw it on a historic map, I was in love. Actually, long since, I have discovered that Pitcairn is a magical place, it's not real. Meaning it represents a place that we all want to escape to at times.
