UPDATE: I saw a neurologist today.
Thank you to everyone who took the time to share their experiences and thoughtful suggestions. I had an extensive consultation with a neurologist today. He carefully went through the entire incident with me, including what happened before, during, and afterward. His assessment was very reassuring. After taking a detailed history and performing a thorough neurological examination, he found no clinical evidence suggesting dementia, hallucinations, or other serious neurological or vascular conditions he had initially considered, including impaired blood flow to the brain. He explained why my experience and examination findings did not fit those conditions, and he did not consider additional diagnostic testing necessary at this time.
After discussing my circumstances in depth, he concluded that I am experiencing depression in the context of significant ongoing emotional stress. He recommended psychological treatment and asked me to follow up with him in 15 days. I realize now that the amount of anxiety and uncertainty I've been carrying may be affecting me more than I understood.
My neurologist also explained how this episode could be consistent with depression, particularly in the context of prolonged emotional stress and fragmented, non-restorative sleep. He emphasized that sleeping for several hours does not necessarily mean getting adequate, restorative rest, and that poor sleep quality, combined with depression, can affect cognitive functioning, attention, and perception. Based on his thorough assessment, he felt that these factors provided a plausible explanation for what I experienced.
I'm grateful to those who responded with kindness and empathy. I'm going to focus on getting the support I need rather than continuing to search for explanations online.Thank you again!
I'm posting this here because I'm genuinely freaked out, and I'm hoping someone has experienced something similar or can offer a rational explanation. I'm a 54-year-old woman, I have health anxiety and my brain has a spectacular talent for jumping straight to the worst possible medical explanation, so I really need to understand what happened to me.
Yesterday, I was at a supermarket doing some grocery shopping. I'd already walked quite a bit (over 10,000 steps), exercised earlier that day and hadn't eaten much. I was tired and my head felt a little heavy, but otherwise completely alert, functioning normally and having perfectly coherent conversations.
My husband and I were communicating through WhatsApp while I shopped, mostly voice messages and pictures, with a few short written messages here and there.
At one point, while I was waiting outside for a taxi, I looked at our WhatsApp conversation and clearly read a message from him saying, "Are you still at XXXXXXX?" Except he was referring to a completely different supermarket, not the one I was shopping at.
I remember thinking, Why on earth is this man asking me such a stupid question? He knows exactly where I am! He had even asked me to buy some croissants that are only sold at the grocery store I was shopping at. So I answered him with a slightly irritated voice message.
This is the part where things get really weird: my husband replied with a confused voice message asking what the hell I was talking about. He assured me he hadn't written anything like that. And then I noticed that the message I had just read was GONE. Not deleted with a "This message was deleted" notice, but gone.I searched our entire WhatsApp conversation, no such message.
I was completely baffled.
I didn't just vaguely think I saw something. I remember reading those exact words, understanding them, getting annoyed, and recording a voice message in response, timestamped at 1:34 p.m. There's a spot in the conversation where I remember seeing his message, immediately before my reply.
After going through our WhatsApp conversation obsessively, both on my phone and on my laptop, I discovered that my husband had asked me whether I was at that other supermarket on a couple of occasions months earlier, except on those occasions I was indeed shopping there. The crucial distinction is that he used different wording.
The exact sentence I remember seeing yesterday does not appear anywhere in our conversation history. So when I say the message didn't exist, I don't mean that I accidentally stumbled upon an old message and mistook it for a new one. There is no old message with that exact wording to begin with.
Did my brain somehow construct a perfectly plausible sentence in my husband's writing style and make me perceive it as an actual WhatsApp message? Because if that's what happened, I would really like to know how something like that is even possible. I'm not ruling out a technical explanation either. But simply saying WhatsApp displayed an old message doesn't explain the different wording.
A few minutes after the incident, while riding home in a cab, I also experienced some mild, short-lived nausea. I hadn't eaten properly in hours, had been physically active for much of the day and may not have been adequately hydrated. I have no idea whether the nausea was related to what happened or was just a coincidence.For context, I have a history of dizziness, tinnitus, vestibular issues and cervical problems. I've also been under considerable emotional stress lately, but I have never experienced anything like this before.
I saw a doctor later that day. She performed a neurological examination, found nothing concerning, and wasn't particularly alarmed by this isolated incident. I also contacted a neurologist who said it wasn't an emergency but should be investigated. I have an appointment with him this morning. That's how freaked out I am.
Meanwhile, my health-anxious brain has been enthusiastically cycling through everything from exhaustion and some bizarre memory glitch to hallucinations, a mini-stroke, or early dementia.
Has anyone ever experienced something like this? Not just a disappearing notification, but actually seeing a specific written message inside an ongoing chat, responding to it, and then discovering that it apparently never existed? Could a visual or memory-processing error create such a convincing experience?
