This hasn't happened to me in T, but I think it's a stress/anxiety reaction, it's happened to me before - one instance was when I was with my mum, and she was flipping through the IKEA catalogue to find something.. I just felt like I needed it to stop! The sound and movement of the pages: flick flick flick flick flick flick!!! I don't know how I didn't scream - I did have to close my eyes... It's happened to me in supermarkets where suddenly everyone is moving too fast and too close with their trolleys and I start to feel the panic rise.. I think it's something to do with stimuli and how we can't cope with too much when in a highly anxious state. Sometimes even the sun just feels too bright and colours too sharp or noises too loud and I have to go and lie down in a dark room.
