"As HOT TUNA said... dream recall can be more important than lucid dreaming per se. Actually, memory is a crucial issue in many things we do. Certainly salvia and the other disso's have this dream recall factor. I view it as at least partially built into the nature of travelling between worlds/dimensions/dreams. A metaphor could be that there are "customs" at the border and certain things are not allowed to be brought with you in certain quantities. Not drugs, but memories. An experienced dreamer is like a memory smuggler. (it is just a metaphor)"
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
