Hi Daniel17
I don't pretend to know all the bible, but I have a hard time believing that it's written in the bible that if you dream you're falling, you're in sin or on the wrong path! God is a loving Father. If you have sin in you're life that you're not aware of, I don't believe God would use the "scare" method to make you aware of it. I believe God speaks to us through His Holy Spirit, in a still, small voice, manifested sometimes maybe by an uneasy feeling in the pit of your stomach. There are of course other ways like an audible voice in your mind, a certain scripture in your time of prayer, profecy, a friend telling you he or she has heard from God regarding you, etc. Whatever the method, I would sugest going to God and asking Him directly in prayer. As far as dreams are concerned, although some dreams may be from God, I don't believe this particular one is telling you anything! If you want to be certain, however, pray about it. If there is anything wrong, the Lord will show you. Just don't be afraid!
