Watched this on Netfix under the name "Lucid Dream". I don't usually watch Korean Dramas, but this was short and sweet so I thought I'd give it a go (and I love a good gender-bender storyline). The story is interesting- Two people share a dream of their love story in a past life and try to find each other. This has all the drama cliques, a crazy girlfriend, a broken down lift scene, slow motion hugs. Basically everything I love about Asian dramas. The acting was very good, couldn't fault it at all. Seo Ji Hye was very good, I find that the protagonists can sometimes be over the top and comical, but she was very impressive. Although, as an engaged gay woman I found the protagonists "curse" to be hilarious. The music really really started to grate on me, the same song was played every 20 minutes. I ended up having a migraine with the song playing over and over in my head like some kind of torture. I would 100% watch this again in the future, it's a very easy drama to watch. While you do need to be paying attention to really understand the dreams, the episodes on netflix are very short and sweet.
