I was at Disneyland with my boyfriend on a hot day. We were there all day and I bet we did not eat and drink enough. We were waiting in line for a ride and all of the sudden this heavy horrible feeling came over my body. I told him we need to leave now. By that time I blacked out my boyfriend luckily caught me. He put me on the ground and was calling my name over and over. I finally started to hear it and opened my eyes but they closed again soon after, I could not stay conscious. Some one sat me up and that kept me awake but the weird part was everything I could see was grey??? I could not see in color for a few minutes until it came back to me. The second time I fainted was scary because the same thing happened but my eyes were open during the fainting. I could not stand, talk or anything but I could see?? I watched my boyfriend grab me and carry me to his car. we were walking at the time.Any feed back??
