There is no such thing as negative awakening. However, what do we do with it and how fast we want to progress it may create negativity or positive experience. There are some people that upon realization become upset with the environment, society or humanity, and that is what creates total discomfort and make us believe that awakening is not really a great experience. About such individuals, we can say they are awakened not at the right time for them, and that was only their decision. For instance, we can see people going to South America and trying to use different plants as self-inducted drugs to create a spiritual experience. Many times the result could be catastrophic, especially for egocentric people. Anger and desperation may come to them, and many times negative entities may influence them. In my humble opinion, every awakening must be happening at the pace that the individual can cope with. Time is not relevant after all.
