Yesssss....
Possibly worth noting -- I did have vibrations, but it was more like an almost pleasant humming sensation. I've noticed this over the course of my experiences; when I was just starting out, the vibes were very harsh, like a foot falling asleep but over my whole body, with loud roaring sound effects. Now, while spontaneous near-exits have been a lot more rare, when they do happen the vibes are mild, almost as if they've increased in frequency. I wonder if this is an effect of energetic development? Yes! Yes! The more you develop the less transition-shock there is- and then someday you get no vibrations, because your consciousness learns to 'tune up' as you transition, so you don't perceive the frequency shift.
So yes, it means development. But it also means you have been doing it more often than you remember. Or at least the second part of my answer is purely opinion.

In any case my spontaneous exit symptoms have gotten to be months apart, so it was really encouraging to have happen right after I started thinking about pursuing it again. Your intention is also helping you with the third eye stuff. Do you regularly do energy work?
