lucid dreaming group and workshop, any advice?

hey folks, sam here. on wednesday im making a lucid dreaming workshop and group forming here in copenhagen at a local free space. It looks like we are going to have a good turn out and i want to do a good job. The workshop is going to be based on user input and the idea that everyone teaches each other.

However part of the workshop has to be set and im looking for the best video to simply explain lucidity and more importantly how you can get started straight away to folks who are new to the idea.
Do you have any tips?

and what would you reccomend are the most important things to discuss at this first session to get people inspired and up and running.

I have asked people to bring blank books (their new journal) and from there we will see
anyway any help greatfully accepted.
sam :)
