Did I have a sign from God?

At Church, the Pastor told us that God sent signs to Zedekiah to warn him of his wrong-doings. Recently, I had a dream that everyone in my family, except me, got raptured. I was so scared. I pray daily, I go to church almost every weekend. I don't envy people, nor do I sloth or be greedy. I don't lust and I take Jesus as my Savior and let him in my heart. I had a dedication at church. Am I doing something wrong? What should I do?
