Nearly a holiday spoiler

I'm in the office in Mayfair on the 21st July and it's mid-afternoon. The office is always quite stuffy and airless. I start detecting the start of an aura and that's not good. I try to ride it but this time it won't go away and I realise that I have to warn the others in the office. I tell them that I think I'm going to have a seizure and then I sit down on the ground and try and breath rythmically and slowly but it's beating me. Some of the others in the office come over to try and comfort me and one holds my upper arms gently, trying to get me to relax. I can't, and I feel like I'm overheating with people surrounding me. I don't remember a lot of the rest of this but I apparently started giving out instructions (not quite orders), which included soaking me in cold water to cool me down. Someone says that they should call for an ambulance and I say that there's no need, but they call one anyway.

There is more to this story, but most of it is not in my memory. More as it comes...
