I do and I dreamed about it. Whenever I think about it, it feels fresh in my mind.
Then I start becoming emotional about it. In one of my past lives, I was buried alive. I remember not gettng out of the closed casket. I don't know how deep I was buried. But I was buried with another person underneath me but they were already deceased. I was bounded around my wrists and my ankles. Some people beat me up and buried me unconscious. Unfortunately, I woke up inside the coffin with very little oxygen. I tried to fight my way but I got so tired and I died. This was a very traumatic experience for me. Whenever I think about it, I start getting emotional. This past life affected me to not trust people that much. I'm currently working on healing myself.

Do you remember any of you past lives? Give details about it please.
(No jokes)

I think its 8%. With 2 die 1/12 chance = .083 = 8%
but im not sure when they use the words 2 or 12 so that means 1/6 chance i think which would be 16%. but there is no answer with 16% so im lost. Please help, thanks

lets say two inputs go into a AND Gate |__) , if one is a 1, and the other is a 0, what happens in the gate ? Does the input just dead end since it cant go through or does it just skip the gate entirely ?
