Thanks for all this info, that's awesome!

I have a quick question on the topic of meditation if you don't mind and I hope this doesn't come off too silly - I'm a newbie (started 4 days ago doing 10 minute sessions of guided meditation a day with Headspace) and was wondering if I'm going the right way. From what I understand, there's plenty of ways to meditate and so there are different meditation 'types', if I can call them that. Do you think it is mindfulness meditation in particular that helps with lucid dreaming? Are there other types that will help too, or perhaps even more?
