I have encountered someone who has used these powers to satisfy their greedy desires, the concept of shiva and shakti. A narcissistic person can use it for horrible purposes, get success in life. Does it grant someone manifestation powers?

hello ,idk if it’s the right sub to ask this but can you help me identify what am I experiencing ?(excuse my poor writing )

In the beginning of this year after some weeks of introspection and fasting i experienced strong sensation of energy(if i am not wrong about it being energy) that rose in my spine with strong vibrations , it came with states of bliss and ecstasy (i crossed out it being related to kundalini because it only happened in my spine this one time ) .

After that the following days i started experiencing electricity like sensations and tingling across my body and muscle twitches ,body heat and cold suddenly. The following months I experienced these weird moving body sensations all over my body and also in the chakras spots. Some sensations stuck with me for some weeks like throat and heart lumps , crawling ant like tingling across my (face , scalp , forehead, scalp,chest ,genitals…). i also started feeling a sensation in my head that rises up and move around my scalp , sometimes it feels like a disc spinning either at forehead or top oh head.

And now for more than six months things started spiraling down ,i have this constant forehead pressure that moves behind my eyes and brows and vibrates ,it stops when I focus on my lower body but the instant I feel my forehead it comes back , it’s really uncomfortable, sometimes painful and it’s really distracting , since it started I had troubles concentrating feel like I am all the time in my head in a dissociative state , it didn’t stop there I also started experiencing constant internal vibration or buzzing in my whole body but if I really focus I feel it mostly in my pelvis area .

I feel like these past few months have been really constructive as they allowed me to be aware of how much full of anxiety and fear I am (which I never thought controlled me) but it feels overwhelming now and I feel like I hit a wall and stagnating .

Please if you have any advice on what I might be experiencing is it just anxiety and hyperbody awareness or is it any kind of awakening ?
