Essentially, you get violently ejected from your body, across space, time, and dimensions. All of your senses grow extra senses and become one. All time is happening simultaneously. And every possibility that can exist does exist. You live a million lives and die a million deaths in every breath until you surrender to it and let go. Then you break into this giant void with a huge ball of gaseous, ethereal light. And you are a smaller ball of the same. It communicates with you through pure intention. Conveying everything. And it helps you.
I came back to my body, laughing and crying simultaneously. A white hot ball of love hit my chest and I could suddenly feel again, after nearly a decade of absolute emotional deadness. I had realized we are all God. And our consciousness is eternal. Once you realize how eternal you are, you have only eternity to cope with.
