Can the water molecule cross-link mast cell receptors?

[KosherDill]

An allergy is defined as mast cells degranulating because a molecule cross-links the IgE (immunoglobulin E) receptors, causing the mast cell to degranulate, releasing histamine in the process.

There is a person who keeps getting in the news every few years since her birth by claiming she has an allergy to the water molecule. She claims she can only drink milk or orange juice, and she once mistook a bottle containing water for a bottle of juice, and accidentally drank a sip of water, allegedly causing her to go into anaphylactic shock which only resolved after a dose of adrenaline.

I have very strong doubts that this is a real allergy, rather than something going in this person’s own mind. Being allergic to water is like being allergic to life itself.
