Thank you for sharing this knowledge.
I undertook a 10 day vipassana meditation retreat one year ago. I wasn't very advanced in my meditation practice at all and undertook vipassana on a whim for the experience not really thinking it through very thoroughly. I noticed after maybe the first 2 days I had feelings of DPDR (though I didn't know it was that at the time) I felt I was highly aware and seeing very very clearly. I thought it was an amazing effect from the meditation. It wasn't until I left the retreat and a day later really felt I was having an out of body experience, which never left me and I later learned my feelings could be described as DPDR - which I have never had before. I became incredibly frightened and fearful of this state and had no idea what had caused it or how to help it.
I practiced, and still to this day (living with this for one year now) practice grounding techniques such as pranayama and asana. I had not been meditating since the vipassana retreat because I was so frightened that it caused me to become so detached that I didn't want to worsen the effects. I know this is driven by anxiety, but you can understand my thought process.
I'm unsure, but maybe I unintentionally awakened this dormant energy you speak of. My experience aligns with a lot of the 'spiritual awakening' symptoms, which most are very similar to DPDR. I've found it incredibly difficulty to function day to day, unable to work, have just recently built some confidence in terms of socialising and do simple tasks that I can manage.
Do you have any further advice around recommendations to assist me or insight into why I might have experienced this?
I can totally understand the physical and mental symptoms that you are experiencing. I have tried most of the traditional as well alternative treatments that are available
May be you did something that indirectly created much pressure in between eyebrows. This has led to some more symptoms.
Now it is really good that you are practising Yoga asanas. They definitely will help you to ground yourself. I have mentioned the specific exercises.Please go through them. Try adding them to your daily routine.
When it comes to Pranayama you should do slow exhalations. Avoid forced exhalation. This rule is particularly for those with DPDR. Use this same rule while doing asanas.
About the imbalance issue you can read about the 3 knots along the central channel. I cannot write much about it here because I think this forum is more about drug induced issue but may discuss in person.
PM if you want.
