All people have the 6th sense, it is just latent in most people because sadly these days people pay attention to their physical bodies and ignore their spiritual one and then society wonders why there is so much depression etc.
It's nothing to be afraid of and can be helpful in a lot of instances. I use it frequently to help me in my sitch with Andy and the kids.
Here are some pointers for telling whether a dream is likely to be telepathic:
1. Telepathic dreams are always in colour. 2. There is a clear storyline to it, usually with a beginning, middle and end. 3. The message in it is very clear, e.g, if your XH tells you something and you remember every word, that is likely to be a prophetic message. 4. The same dream keeps repeating - that is a sign that your subconscious is trying to tell you something and you haven't got the significance.
Non-prophetic, or dreams which don't come true and are either release or processing dreams, are often black and white, flitting from one scene to the next, in no logical order or that you have difficulty remembering. These types of dreams aren't likely to be particularly significant.
This is just a rough guide, but I hope it helps. As I said to the other poster, if you journal your dreams, you get better at remembering them and decifering which ones are telepathic. Practise makes perfect!
