Lucid Dreaming mentioned in Scientific American

In an article about vegatative state there is a graph that compares different states with awareness and wakefullness. Coma was at the bottom left (least aware and least wakeful) and being fully awake was at the top right. Lucid dreaming was about a third of the way up the wakefulness axis (same as REM and deep sleep) and most of the way up the awareness axis (just between being fully awake and being drowsy.)

I left my scanner at school so maybe another subscriber could scan it the graph in.
