It seems that mood swings are quite common in a kundalini (awakening) process, and perhaps especially if it turns into a spiritual emergency.
During the initial awakening phase, I wouldn’t really call it mood swings, but it was a sense of shifting from bliss and expansion to pain and contraction, over and over, and it was quite dramatic at times. This happened mostly in my teens and early twenties.
Then, there were several years where everything seemed more stable.
And more recently, in the darker phase of the dark night of the soul, it’s been more of what I would call mood swings. Shifting from depth of terror and dread (a couple of years back) or contraction and pain, and a sense of ease and even joy.
Most of the time, the shifts happen within the same day, each one lasting one or a few hours.
Rereading this, I see that “mood” doesn’t quite cover it. It’s more a swing between a sense of ease, joy, bliss, expansion, and pain and contraction, and the specific flavor of each has changed over time.
Of course, one invitation here is to recognize that it’s all coming and going as content of awareness, and that awareness itself is always here. Another is to meet what’s coming up, including my reactions to it, in natural rest, and with kindness and even love. And yet another is to identify and questions any assumptions I have about what’s happening. It’s easy to say, and not always so easy to do. I still don’t do it consistently, and that’s part of finding a more genuine humility in all of it.
