For the longest time, my friends made it a joke of asking if I could picture an event and if I could see it they automatically knew it wasn't going to happen. I've never been good at being able to tell what's going to happen, but I've always been able to tell what will NOT happen. I'm wondering if this is a gift/curse or just a problem I'm having with my third eye vision.
I think you are still forseeing the future and are a psychic but maybe you either can only see what won't happen or you have just had some bad luck with your visions. For a while I could only predict bad things in readings for people but it eventually passed.
If you think you're having issues with your third eye, I would suggest working with it (and your other chakras as well for balance purposes). Doing so can improve your psychic abilities and may help with any issues with them that you're having.
I think it's less magical and more related to probability. I mean, when it comes to the future, there's only one thing that will happen- and that's what does. That means there are a billion other things that could have happened but didn't. So, which of the two do you think you're more likely to guess?
