ANSWER - I'm going to make the assumption from what you say here that you believe in reincarnation. So rather than debating whether reincarnation is true or not, we'll assume for the purpose of this question that it is and explore what you ask from there.
I have to be honest - you come across as rather egotistical with the suggestion that you may be too wise for the modern world. That may not be precisely what you intended to say but it is a dangerous step toward a slippery slope of thinking. Once we start to believe that we know everything and have nothing to learn from others then we fail to grow as people and we fail to take advantage of all the opportunities each incarnation has to offer us. The most common interpretations of reincarnation involve the idea that the soul learns a new lesson in each of its times on the earth. If you fail to look for the lesson - and part of that is seeking the wisdom of others - then I'd suggest you are not making the most of being here this time.
You say people don't understand you but you do not say what steps you have taken to promote understanding between you and them. To truly make the most of each life you need to make an effort to understand others and be understood. Taking the lofty view that people don't understand you is negating your own responsibility to help people to understand you. Anybody can claim to be misunderstood, there is far more value in building relationships with others and looking for ways to understand and learn from what each other believes. It interests me that you describe yourself as a blunt person - bluntness can of course be an exceptionally honest quality but it can also be an indication of lack of tact with regard to the feelings of others. Think hard about whether being more conscious of the feelings of other people could be the lesson you need to learn in this lifetime.
Precognition incidentally is relatively commonplace - I have no doubt that you get an occasional glimpse into the future but I wouldn't take that as evidence that you have nothing left to learn. Beware of falling into the trap of thinking that just because you are gifted in one area you have no ignorance in others.
I appreciate I'm being quite harsh with you but I genuinely think that instead of pondering whether you do fit into today's world you need to make the effort to fit in and to seek out the things you can learn from the world and the people you share it with. You may well be an old soul who has gone round the reincarnation block a few times but that doesn't mean you won't learn something new each time you do come back. And equally if you have all this knowledge and wisdom - get out there and start sharing it. Find a meaning in your life by helping others. That really will bring some value to this incarnation.
