No 'believe' or 'disbelieve' on such topics, only whether there is evidence or not. I have seen just enough myself now which would mean there is an independent intelligence guiding our lives and actions, as for instance I have been given detailed information in dreams which led to me finding things I would never have been able to otherwise, and in so many complex steps it would have been impossible for them to have happened at random.
One for example was dowsing was used to find something on a map, Streetview found it exactly where mentioned, a photo was posted online, someone else saw the photo and remembered the same item they found years back, put it online and I went back and found it (an obsolete road sign 50 years after most had been removed) was still there. The original one I found was the same but only a museum exhibit so not a genuine collectible as not in use.
Another sign was seen in a dream with a damaged end, then I saw an intact one in a book, and then found the exact one with a damaged end exactly as the dream, meaning the intelligence was able to find one, tell me about it and then direct me to it. It's far more complex than a simple coincidence, and happens too many times to be chance as well. There has to be an intelligence guiding it, it may be our own or a universal one.
