Weird thing is, I haven't been doing my awareness training for a couple days. Maybe my brain just needed a break.
So it lasted about 20 seconds or so. I've recently started going to the gym so I've been 'mirin myself a lot. Well I ended up doing it in my dreams and my body was colored weird, like vains were yellow and I had a red tint. So I knew something was wrong and pushed my finger through my hand, took a bit of effort but I got it. So it wasn't very vivid but I rubbed my hands and in a couple seconds it was fully blown vivid.
But here's where the weird part is that I have a question on, it was very hard to breathe in the dream, like I had just run a marathon and was struggling for air. Soon after I woke up. What should I do about that?

My environment
Bedroom
About 4-5 AM the lucid occured
Very cold, I had the fan on and it was freezing outside. Maybe that's why I was breathing so hard? Will have to experiment with temperature and lucid ability
