I keep having dreams about snakes?

It all started when I was 13 years old, The first snake dream I have ever had. I had a dream I was in my room, And I came out to go to the kitchen, My grand mother who has passed away recently to stage 4 lung cancer was in the kitchen washing plates, As I turned the corner to walk into the living room I seen a HUGE mosh of snakes all over the place you cant even see the floor it was ateast 4 inches thick of snakes all crawling around on each other slithering around. I yelled out "What the ****!?" and my grand mother replied with "Walk through them, They wont hurt you, They cant" and I woke up. My brother, My mom, My girlfriend all had dreams I was attacked by a snake and killed. 6 months after my grandmother died, I have had dreams about snakes for 2 weeks straight now, I will walk into them no matter what, No matter where I am they find me, But they dont hurt me, I can pick them up, I can touch them, And they will not attack me, I had dreams for 2 weeks bout snakes, sometimes 5 snakes at a time, to just 1 snake at a time, And none of them has attacked me when I touch them or pick them up, Even poision snakes like Cotton Mouths and water snakes. Just tonight I had a dream about a snake again, This snake was uniqe and I have never seen a snake like this before, It was light slate gray, and had black rings around it every inch or inch and a half it had a half a inch black ring around its body, It has black eyes, And a solid black mouth, It looked at me and I looked back at it, I didnt touch it because something about the snake I didnt like, It didnt seem like any other snake in my other dreams, My girlfriend appeared out of no where and came up beside me and picked up something that was beside the snake, As just reached down to pick it up the snake attacked her, She rushed back into the house frighten and scard, I looked at the snake and picked it up, And it didnt hurt me, It didnt attack me. If your wonder why I picked the snake up after it attacked my GF is because I wanted it to get Anti Venom for my GF. But why am I having these dreams? What do they mean? I am christian also, My relgion believes snakes are the devil, Does this mean the devil is after me? Or is he protecting me? Or is it something else? Please respond and let me know cause this is starting to get scary, What started out as snakes not hurting me, Is now at the point to where they hurt the people I love.
