I always feel tingling in the palms of my hands. I have a constant hum in my ears. Whenever I meditate, I immediately fall asleep/go unconscious, even when I’m not tired. What does all this mean?
It’s what we call Ascension symptoms. All of this is very common as our consciousness is evolving. The tingling sensation is you feeling your own energy body for we are all made of energy according to quantum physics. Constant hum is attributed to Pressure from our bodies rising and falling in density. As for meditation, this can happen because our mind moves into a deep alpha/delta state which is quite similar to the state we enter into sleep. It’s about training your mind to stay awake as you enter into the alpha state otherwise our body kicks into gear and goes into a sleep. It could also mean you need rest and your body is telling you so intuitively.
