Hi Zimmer,
I can agree with most of what's been offered here. Here's how I would sum it up had nobody else said it first, for what it's worth to you.
While our dreams are very likely NOT prophetic and I don't see much evidence for a pre-trib rapture in the Scriptures personally, your dreams are an opportunity for your thoughts to come together to show you things that you are either aware of or maybe not paying attention to, to bring certain concerns to the light so that you manage them. So, yes, it can be a blessing to you to have had this dream, BECAUSE our relationship with God is the most important aspect of our lives, and from this dream it appears to me you are looking at this with concern to want to secure your basis of building your life. You are looking at the fact that we can't build on a lie, even in the name of religion, and you are looking at the fact that you might not be living up to what you are thinking are the expectations. Good for you for bringing all of this out onto the light, out onto the table. Don't be afraid to inspect every aspect in the light.
Religion hasn't always been true to the Scriptures, but the word of God (what God said in the Bible) and the Word of God (Jesus Himself, as the Son of God and every word that Jesus spoke) hold your answers. It is actually up to you what you build of your life and Jesus made it clear that in the end He will separate out those that acted righteously from those that didn't. By saying this I'm not saying you save yourself because only the sacrifice of Jesus could atone for our sinfulness. But in your dream it appear that you are looking at what you need to do, and I'm agreeing with the Peter in the Bible that you add all diligence to make your calling and election sure.
If I were in the place I'm imaging you are from your brief post, I think I would want to hear encouragement that it sounds like your heart wants to fully turn to God, and God doesn't turn away from those people - that's what He wants from all of us.
In order to see what that means, read what God said. I'd encourage you to read through what God said. You could start in Genesis to see what God said to Adam, to Noah, and to Abraham. You could even start in Deuteronomy to see what God said to Moses to tell the community of people. At that point, once you've read what is called "The Law," jump over to see what Jesus said because you'll find that He says the same thing, straightening out the distortions of years of religion. As you ponder what you are reading, try to use the words of God to set aside the subsequent years of "Christian" religious history since the time of Jesus, as it's unlikely we evolved to a better understanding than what God told us from the beginning, and He hasn't changed His mind about His message in all these years. Now take that understanding back to the book of Proverbs and gain some additional ground on the good sense that our loving God offers us. Read the history in the Bible to see what people did as they worked through their reactions to God (mostly from disobeying, but sometimes by obeying) and read in the prophets what God told them as they went through those situations. A good commentary will help you put the history and the prophets in parallel to help you understand. Reading them separately might have you wondering why God was mad, but putting the anger together with the awful evilness of what people were doing will help you make sense of it.
Try building on that, which should have you building on the sure foundation of doing the right thing (agreeing with God in the process) and of having a better discernment what the right thing to do is.
He is no fool to trade what he cannot keep to gain what he cannot lose. Be encouraged that this will be well worth the life of effort you put into growing closer to (not the God of our imagination or the God of religion but) The Eternal God as He is.
