Hi Chuckles.

I think Yoshi mentioned already the most important things, but what I can tell you, for me it is very similar. My heart feels like it is beating a thousand times in a second, but don't worry about that. See it as the beginning of your lucid dream. When you start seeing Pictures, calmly observe them until they form a scenery. Just let it happen, the dream will form around you after a while.

KingYoshi:Make sure you perform a RC when you sit up
VERY improtant!! WILD's start fairly often with a False Awakening", so you might acutally sit in your dreambed.

Cheers
