When my daughter was young, around 6 or so, and would get a fever, we would pump her full of tylenol.

When we went down during the night to check on her, she would usually be sitting halfway up in bed with her eyes half open talking to people.
SPOOKY.

I wonder why it is possible to speak in non-lucid dreams, but is not possible in LD's.

You could leave you tape recorder on and dictate you adventure as it happens. Maybe you could use one of those sub-vocalization microphones that commando's wear around their neck.
