Remembering seeing him? o knowing if he's been there at all?

So, I've been looking through the respuestas to different preguntas for a while now and taking some of the advice. The thing is that even after 6 months o so, I haven't seen him (or don't remember it). I've only had the slight feeling of flying in my sleep. I've wondered if tu guys have tips on remembering your adventures and/or any tips. Thank you!
