There are people who believe so much in dreams amd their spiritual interpretation / significance. And the truth is, this works for them, and for some that doesn't believe in it they might never really see the importance of remembering dreams. Now will if we were in a world were our dreams could be recorded and replay, how will such a world be, will it be good or a nice idea to us.
Well, i will say that it all depends on how we see and give importance to dreams. Now for people that believe so well in dreams, it will really be helpful to them. Why am i saying so ? Dreams serves as a guiding light to some people, it helps people overcome some issues even in real life. To some people dream is a means were God communicate or reveal things ( the future or past to humans). So living in a world were dreams are recorded and replayed will really help some people that gives importance to dreams.
I remember a friend of mine who told me a story about something that happened in his life a year ago, it was still a conversation related to this dreams of a thing. He had a serious accident, that nearly took his life, but God in his mercy served him. He told me that the week before that accident occurred that he had a dream about such happening and when he woke up, he couldn't remember the dream and to some extent, he thought it was a malaria dream , over here we call it ndap utu eyen. According to him, it was immediately the accident happened that he recalled the dream and it happen just as he dreamt . He told me that, it was only God that served him.
Now, imagine if he was able to record that dream, don't you think he would have prayed about it or avoid embarking on a journey that day ? So as i said earlier, being able to record and replay dreams if we forget, would go along way to save some of us from problems.
