What I perceive to be my kundalini awakening was initiated during a dream and continued after I woke up. I heard a loud cracking sound and was shot in the head by my biological father who I was chasing after in the dark (I think) and felt a sensation of liquid pouring out, although with no pain, then intense tingling sensations. Right after that, I woke up out of sleep, and continued to have the same feelings in my head. They got more and more intense and at some point the purely cranial sensations transformed into energy ripping up from my lower spine/perineum region through my body and exploding out of my head. It felt like a fire hose of energy shooting up through me. Sometimes it was a continuous flow, but over time it become more like a pulsating energy, sexual, waves of orgasmic bliss, over and over again shooting out the top of my head in the most beautiful, whole body feeling you could ever experience. That first night, it seemed to go on for hours unabated. When it finally started to lessen and I felt myself falling asleep, it would start ripping up in all its intensity again just before I hit the boundary between wakefulness and sleep. It did this same thing over again and again all night.
It changes your perspective on what it means to actually "sleep". What is really happening here? Do we step into some other spiritual or astral realm and have another life that we are only vaguely aware of in this one? If we have dreams like this and an event during sleep triggers an event when awake, like a kundalini awakening, what's the nature of the connection between the two? It's just super fascinating and sucks me in with awe and wonder about what's really going on in life.
Interesting story, I've also experienced activations during sleep and dreams. The first one I remember was during a thunderstorm. There were 3 rolls of thunder and each time the thunder rolled, I heard the words, "personal power", "personal power", "personal power".
I was so confused afterwards. Those words didn't mean a thing to me at the time but it marked a turning point in my life which I will never forget.
