I think you have described Raymond’s inner journey, but there is no outer one to hook it onto. In other words, what is Raymond doing now and how does he realise he had a past life. I mean, OK he believed in reincarnation before, but if he doesn’t now, what makes him remember? Does he experience a cathartic event? Does someone tell him? In order for your audience, let alone a producer to be interested, your hero must have a clear goal at the beginning of the film and he must achieve it by the end. Or not, if it’s a tragedy. His belief system is his inner journey. Hope that helps.
