Has anyone who experiences\\has experienced visual hallucinations ever tried VR and found that their hallucinations stop or are at least significantly reduced? 

My sister, who has lived experienced, used to experience a lot of constant, intense visual hallucinations that were often just really distressing and exhausting. We bought a VR headset (this was a few years ago) and it came with a load of different scenes/immersive experiences, including one of a beach, and when she tried it, she wouldn't see anything she normally did in her hallucinations and it actually gave her a break and some respite from the distressing things she would see (as long as she was somewhere calm like a beach). I remember her telling her care coordinator this, who thought it was amazing how helpful it could be to her and possibly others.

I ask this as I'm a journalist writing a feature on emerging digital therapies for mental health for my journalism MA final project, and I want part of it to focus on how VR can be effective for people suffering with psychosis or schizophrenia (there's quite a bit of research and trials on the matter). It would be great if I could interview my sister or just include her experience in the piece, but unfortunately my university doesn't allow us to use family or friends as interviewees. So I was wondering if anyone else has had a similar experience with VR and their hallucinations who could attest to this? Or even if you just find VR really helpful to escape when your symptoms are particularly bad. Conversely, if you find the opposite and that it actually makes symptoms worse (and you'd be willing to share that), that would also be equally helpful.

I'm also really sorry if this goes against the rules to ask this here – I did refer to the list for writers of consenting users for interviews (which is really helpful btw!), but as this was a really specific question I just wanted to see if I could ask it here. And also in case someone might find her experience useful/interesting for themselves :) Thank you so much!
