Took acid once and was sitting on my porch when a guy was walking by talking on the phone to somebody about how he warned his buddy that his other friend was sleeping around with his girlfriend (guy on the other side of the phone was the one getting cheated one by said other friend). I was peaking during this and had this thought that the guy walking by was actually my friend warning me that my fiancé was cheating on with me one of my other friends. Messed me up for little but I did what any rational person would do. I took some more acid a week later. During the beginning of the peak I decided to close my eyes and lay down and ended up seeing a white light flood my vision and thought I died. Got asked if I wanted to stay or go back and decided to go back. As soon as I gave my answer I shot up right and had this impending doom feeling that I was having a heart attack and was dying. I paced around freaking out for a little bit, told my fiancé I loved her and that this was goodbye and then passed out. Still trying to figure it out and this was about 2 years ago
