Hello all. Praise the Lord.
Don't worry about your dreams.
It could be Satan, but I'm not sure. Most likely not.
Dreams come from what you're thinking throughout the day. You're a new Christian, we all get scared sometimes. It's like going into a different life, changing your heart completely. It's very easy and understandable to get scared. I've been a lot letely.
Since your thinking about this a lot, you have dreams about it. Here's some advice:
Pray to God. First, lift him in all of the glory he deserves, then tell him you love him. Afterwards, pray to him that you wish to have a peaceful sleep full of wonderful things. Then close the prayer. I also say "I praise you in all your glory, Lord" when I close my prayers. Then I say "In Christ's name, Amen."
Do not doubt that God will give you nice dreams. Know that Jesus won't adandon you like in your dreams. He loves you.
Do this, and God will make sure that you won't have these dreams!
I hope I helped.
