I had an awesome experience while meditating. I'm pretty sure it was single pointed jhana practice but I was also listening to a Mahasi Sayadaw guided meditation on youtube. 

I'm uncertain how I got there but my body disappeared and a white balloon was located where my head should be, no head no body, just the balloon that expanded with the in breath and deflated with the out breath. It lasted 3 to 15 min, I meditate laying down and fell asleep after. I had deep equanimity after for days. 

I'm a DIY noob, just starting to get mediocre at the jhanas. 

I'm open to all guidance. 

thanks

​​​​​​​I searched "balloon head" and couldn't find anything.

I had ballon head a lot early in my practice. Glad you mentioned it. 

Cool, do you have a suggestion as to what Jhana would correlate? I think I accidentally achieved a cessation beyond my skill set.

​​​​​​​Looking forward to being able to do it again.

All sorts of weird stuff happens while meditating. It's just another thing to let go and move on from.

google this to search the Dho -
