Hello Ulises, welcome to the Forum family.
Thank you for sharing your situation with us.
If that dream did come from God, it sounds like He was confirming it the very next 'service' you attended....the pastor could have been confused enough not to understand what God was warning him about, and alerting you to that as well through the words spoken in that dream.
My prayer for you is that if there is a home fellowship (10 adults more or less, plus their children) in your area that is overseen by a Pastor and his wife that has been put there by God, and who will therefore treat you as one of their own family, that God through His mercy and and loving kindness will lead you to that group. Amen.
