Good question ! I think you should first evaluate the type of audience and choose the best context.

Nobody can forget that REM is an important part of sleep, so itīs very likely that the proper context to speak about dreams may pop up to. Also, i think "your" seminar probably will talk about sleep schedules alternatives ( like biphasic, everyman, napping..) and so itīs a good moment to mention lucidity as an advantage or side effect.

And many many other things, like nightmares, which may pop up and provide another very good opportunity.
