Yeah it's a form of dishonesty to claim to be an expert in a particular field and then go on to state your own ideas and opinions in a way that suggests they are scientifically-backed facts, eg by speaking authoritatively and presenting meaningless graphs. I'd say the guy has experienced lucid dreaming sure, but he's no more knowledgeable than most of our regular DV members. He's just putting on a teachers cap and speaking in a convincing sounding manner so that newbies will think he's the lucid guru.

Reminds me of an evangelist.

Should definitely sticky this.

Good thread monkey
