Help!! Ah rmps dissertaion ideas & advice needed

I decided to take advanced higher Religious moral philosophy studies this year in Sixth Year. I've done National 5 and higher the last 2 years. I've studied Modern Warfare, cosmological argument and Christianity through the years. This year, we're looking at religious experience and philosophy of religion. I have no idea what to do my dissertation on, what to title it or how to start it. Any advice from past experience would be much appreciated !!!! love to rmps fam xxx
