I've never had a snake dream, that I recall, but I had a lion chasing me, & of course bullies. In one dream my volkswagon bug (that I had at the time) & I were being chased by bullies & we suddenly took to the air & got away. I remember saying to my car, "I didn't know you could fly!!" I had had many flying dreams, just me, especially during my childhood, but this was the only time I was in a flying car. Anyway, snakes, lions, bullies, whatever, don't they probably represent challenges in our lives, and/or things we're afraid of?
