So, I have had a lucid dream after about 3 weeks of waiting. I had took a nap at a friends telling myself I would lucid dream. So I was soon in a large field with my friend and his brother when one of them pointed out a "scary dog". I look around to see two neighborhood dogs, very big but sweet dogs (one looked like this) So I told them not to worry about them. Then they pointed out another dog which look like a massive wolf,(subtact the 31 and that's about the same) we began to run for my friends house I his brothers and me were in and time began to slow down. I told my friend to get inside the wolf was looming over him, I then noticed his shirt and it was blue one of my triggers so I did a RC and bam lucid for like a second, my dream went dark and collapsed.

How can I prevent this in the future? please and thank you
