its a feeling i get sometimes, kinda like lightheadedness but not really. like im underwater, or in a dream, and nothing seems real. it sometimes gets so bad, that i have to just ly down because im afraid im gong to pass out. also, my heart seems to go faster at these times. im scared, do you know what this is or what causes this? no one seems to understand the way im feeling. i hope ill find someone that does. thanx
