Ecila gave you a great interpretation. Be careful what you ask for sometimes You got the information in such a way that it was very graphic and noticeable That happens to me sometimes.
Something else about your dream, it may not just be your church that you feel like you are conforming to. Your work forcing you to work 15 hours a day is a sign that you feel people pushing you - as well as - the situation at your church. Also remember, that sometimes in churches the whole church gets "stuck" - or most of the people do - trying to fit in with what they "think" they should be - if that makes sense. When a group gets stuck they don't grow and become closed minded.
I'm sorry that you had such a terrible nightmare, but if you felt healing and a message, it should have been worth it
