FOREWORD
I'm a security guard who works 2 shifts in the week at a nursing home. Needless to say, we deal with a lot of dementia patients. Occasionally they will escape and it's the security guard's job to find and return them.

DREAM
I was working at the nursing home and I found one of the residents splashing around in a water fountain just next to the car park. I knew this was out of the ordinary, and needed to be dealt with, but for whatever reason I decided to wait until the morning shift got on site to tell them about it — we could deal with it.

When the morning shift showed up, I told them there's a crazy old bitch splashing around in the water fountain that we need to take care of. They looked at me as if I was crazy and after apparently thinking for a moment, held me down. They explained to me that there wasn't anyone in the water fountain and that I was showing signs of schizophrenia.
At this point I looked over to the water fountain, where the old bat was jumping, from a small step, down into the water fountain and flailing her arms above her head as if she was jumping from a building in an attempt to commit suicide. It was quite disturbing to watch. It was even more disturbing to be told it wasn't actually happening.

I chose to believe the Nursing Home staff and complied with their instructions to stay still so they could help me. There was an immediate, and intense, feeling of wanting to get better. I didn't want to be crazy!

So next thing you know I was in a mental hospital and in a room surrounded by a plethora of tables arranged in a square. At these tables sit a number of Doctors and they were quizzing or interviewing me on my "episode" at the Nursing Home and deciding how they were going to treat me.
When the lead Doctor began asking me exactly what I saw at the Nursing Home — referring to the old woman in the fountain pretending to kill herself — flashes of a very beautiful and young woman's face would go through my mind. Each time I tried to tell the Doctor's about what I had seen, at the Nursing Home, this face would get more and more evil and flash over in my head again and again. Her teeth became jagged, her skin turned an evil blue/purple and her hair got more and more frayed and dull as if it were that of a corpse. I understood that this was my brain, and my illness, trying to stop me from talking to the Doctors. It was trying to stop me from getting better!

Eventually I got the whole story out about what I had seen and they let me out of the room for a break. It was at this point where I woke up, still convinced, that I was insane. It took a while for it to dawn on me that it had only been a dream so for a little while, in my waking life, I was convinced I was a nut job.
If you don't mind a quick read; that's my similar experience directly out of my journal.
