I feel you.
I struggled with WB too, even though I only listened for 3-8s back then.
This is completely normal. The process will take time, but it will get smoother over time once you get more accustomed to the sub.
Use a lot of rest days, space your exposure to Ascension even more sparsely.
Stick with 3-5 seconds for now, it’s more than enough to help you progress from my experience.
Slowly increase it over time when you’re ready.
But for now, cease all subliminal exposure.
Do a long washout until you become normal again.
Assuming that this is from sub, there’s nothing to fear, it’s completely normal.
If you still want to check with a medical professional just in case, by all means do so, there’s no harm in being cautious for unforeseen circumstances.
Mmm sounds like a defensive mechanism with ascension. The script is probably still active and it’s clashing with beliefs that keep you safe. Did you run stage 1 or stage 2?
