If you are in the middle of an awakening of the Kundalini, do NOT tell your MD unless you are positive they understand and know what it is. They will put you on drugs and possibly commit you. But aside from that surrender completely too how you may begin to "feel". This is how the Kundalini will often communicate. Best not to tell family or friends either, as these phenomena are not well understood and can be fear evoking for those who witness yet do not understand.
A transformation of energy and an upgrade for every system in your body is in process. Paranoia can be an effect of the adrenals being hyper stimulated and pumping out adrenachrome or epinephrine. The fight or flee hormones. So you may feel jumpy but see this as a good thing and part of a wonderful, blessed process that many take lifetimes to even come to.
Your kidneys may swell to twice the normal size or more. This isn't painful so much as it is surprising and strange. We as individuals do not typically "feel" our kidneys. So that in and of itself is unusual.
Stay well hydrated (spring water) or what you can find that isn't filled with lab chemicals i.e. fluoride or chlorine and eat some watermelon as this has an almost immediate calming effect upon the kidneys. Eventually they will return to their normal size. But this may occur more than once so keep some watermelon on hand in the fridge.
The celestial music that can often (not always) be heard is natural. Don't go looking for the source -lol. This is an action of clairaudience. Same with the crickets chirping or the flutes or the buzzing of bees. The fingers may become glued into the finger lock. No worries this is another natural Kundalini phenomena.
The various muscle twitches are the result of the increased energetic flow. You are going from for instance a twelve volt system to a ten thousand volt system, so some twitching may occur heh!
Movements behind your chest may be a coming activation and infusion of your heart area. So some emotional fluctuations will happen. Tears of joy and incredible loving bliss will hit you out of nowhere be advised. No worries. Just go with it and as much as possible be grateful for what is happening. Surrender control.
You might be having visions as well. If not this may come and once again gratitude for the awakening that is occurring. Please read and perform the safeties. As your emotional body is also being re- written. Let us know how it goes with you and know that we are here and you are not alone. Others have and are walking this path also - blessings - chrism
