When we have a clearer understanding of our brain waves we can better grasp the answer to this question. There are 4 major brain waves: beta, alpha, theta and delta. When we are using all four together we have what Buddha called "the awakened mind."
Beta is what our society is most involved in; texting, judging, thinking, multitasking, analyzing, calculating. The lower waves are the others and used while meditating, daydreaming and going to sleep. These long slow frequencies are where intuition and premonition flow from as well as psychic gifts. So if you haven't guessed by NOW, it is our brilliant intellect that gets in the way. It's not that you don't have an intuitive hit delivered to you its that you trust your intellect far more than it and override your intuition with logic and/or cautious analysis. Some other interferences are stress - yes folks - stress puts your Mind in overdrive and there is no way your intuition can communicate with you. Same for multi-tasking! Where is the space in your awareness for intuition to speak to you. There is none. This is why I encourage meditation during massage if you aren't practicing it already. Why.... so that you have the experience of emptying your Mind and feeling how great it feels not to be filled up with STUFF. Lastly, alcohol, drugs and over medication can drown out the creative mind-sight that you could be perceiving. Lastly, if your family was highly dysfunctional you probably didn't experience the Truth and therefore mistrust or second guess your inner wisdom. If you want the connection to intuition and psychic gifts ask, do you REALLY?! How bad? What are you willing to give up in your world to surrender to the quiet so that you can have a relationship with your higher self. I hope this inspires you to choose connecting and living from your natural intuitive side. Blessings!
