Prophecy is a term best used to describe a revelation or vision granted or revealed to a prophet or someone of the sort and it has an usually effect on the entirety of mankind and the world. Yes, I can foretell the future and you can channel and control this ability up to a certain limit. The best foretelling comes naturally, when it needs to. However, there are various methods which can be used for fortune telling such as tarot, scrying, pendulum, palmistry, and etc. I prefer to use fire scrying.
As Ethereal said above a lot of people can, most do it through divination (which Ethereal listed a few types of). However from time to time some people, including myself, do get premonitions of what's to come especially through dreams. So no you're not alone hehe :)
Everyone has prophetic dreams and whatnot every once in a while, and anyone can divine.Looking into the future can cause stress at times, depending on what comes to mind. It is best not to dwell on things you may see or feel. But all in all it is a very natural.
I can sometimes have visions to the future and I have a long complicated prophecy. It apso includes this triangle. A dot on each tip of the triangle, and the left side side stood for the bad path, and the right stood for good. Once on track, you can not get off, and at the top tip, it is death. So either way, good or bad, I end up dead and start a new life. I never thought about me being a magickal being before that, and I just recently found this site and discovered that left really is a bad path, and right the opposite. But I have always been able to read signs from nature, but mostly the clouds/ sky. It helps me see visions or it will tell me what is happening in the future/past/present. But yeah, I have a prophecy and I can see into the future with visions and dreams. :)
