Disappearing cliffs and quarries

This is my real experience, along with two other children, and I still feel very incredible when I think of talking with my children, I don't know if we saw the underworld or other world.

It happened in grade 5 of my primary school (90 to 92). The other two children were in grade 4 and grade 2. It was already summer vacation, and the three of us went to our local Red Cross hospital to play and explore around 3 o 'clock in the afternoon. This hospital used to treat terminally ill patients or lepers. It was also said that there was an incinerator there, and the atmosphere was very dark.

Into the hospital, a cement road is on the side slope, soil is a small hill slope, soil ridge is very shortage, many trees, soil ridge height should also is 2 floor height, we want to drill into the hospital along the cement road slope is playing inside, suddenly see the road there is a big bird, and this bird as if injured. As soon as the three of us saw it, we immediately decided to catch the bird, which was also very strange. It was about 2,3 meters away from us and kept making short jumps without flying far, so it slowly led us three children from the slope to the earth ridge. Although many trees were barren, But it will lead us in the faint is the location of a path to the soil on the top of the hill, every time is going to catch it, but it will jump to open some, just don't let you catch, but will give you much hope again, feeling seize it soon, so we follow it up for a walk on the path, slowly along the path of fast in the soil at the top of the hill, Then suddenly the bird flew into the middle of the path, and after a few seconds or so, it felt like it was bouncing down the path again. Everyone was white with fear. Because the path to the top after road suddenly broke, and we are looking down on the trip, I saw the following is a high cliff, the scene around the cliff don't remember, just remember a piece of white, cliff bottom is a quarry, and a too far because it looks like a matchbox size stone of tractors, but didn't see anyone. Because the local Red Cross hospital is we know, there is no quarry and such a high mountain around, the nearest quarry or at least more than 10 kilometers, so if I didn't wake up at that time, maybe we can drop down the cliff along this path, we had three children scared washed-up, hurriedly walk back along the road, just down the slope, Under the slope, we three people think the feeling is very strange, just want to walk around the soil ridge, want to see if you can find the cliffs and quarry at that time, it was already more than 5 PM, we around the soil ridge under a half with the just couldn't see the cliff and quarry, and walk again and then I met a very dense bamboo forest, bamboo forest inside not too sunny, It was beginning to get foggy, so the three of us didn't dare to go further and hurried home.

Since then I have been more than 10 years and I sent you a small didn't dare to go to the hospital, until to the university for several years after graduation, I've heard that the Red Cross hospital have hurt a lot of the old buildings, also planted a lot of peach trees, used to hold peach flower festival to attract popularity, only went once there, but we still can't find it when we see the cliffs and the quarry. Over the years, whenever we talked about this as kids, we always wondered if we were looking at the underworld or some other world, because all three of us saw this cliff and quarry and almost fell to our deaths, so we couldn't have been hallucinating as a group, could we?
