I thought about it, and most of my skills include either location-specific knowledge (like Estonian forest herbs) or sharp and heavy objects hard to transport (like window repairing, woodcarving, or succulents). also, I'm afraid I'm much better in one-on-one-conversation than giving presentations.
If, however, there is time and enough interested people, I could talk a bit about dreaming. I dream of doing a dream-workshop, with theory and practice of natural sleep remedies, bits of mindfulness meditation, lucid dreaming etc. but it woild take way too long (a day and a night), and need some serious focusing on the subject.. but I could talk a bit about the different practical and theoretical approaches to dreaming, and share some ideas.
It doesn't take much preparation on my part, so we can see if there will be time for this topic as we go along, right? I'm running of to Estonian countryside for the weekend, and will possibly have more ideas by the start of the new week.
