dark lucid dream

Last night I was trying to WILD and I think I just passed out, but found myself in a sort of lucid nightmare... It was'nt too scarry it was just me in my house I was floating around alittle bit and was affraid that something scarry might have poped out and attacked me so I left my house and started to become non lucid because I did not have a chance to stabalize it. Is there any way I could make my dream brighter and non scarry or do I just have to suck it up and if something scarry happens tell myself its a dream?
