I was travelling with my mum on a train late one night, the time was around 12 midnight, the year was between 1985 to 1990 i was about 13-14, i was looking out the window when i noticed coloured lights level with train at about 100-200 meters away, it was hard to tell exactly cause it was so dark. at first i thought it was a truck(semi) with trailer lights on,but then i thought about it and the hi way was on the other side of the train, then i thought it was a farmer having a party with lights hung up around his house, then i realised that if it was a house or stationery object that it would be far behind the train, then i thought it might be a refection of something in the train, so i cupped my hands up close to the window to stop any light coming from inside the train, that's when i noticed that when the lights came to a cleared paddock it would descend and when it came to trees it would then go up,that's when the hairs on the back of my neck stood up i sat there and thought of everything it could be but everything i thought of it wasn't, i sat there for about 5-10 minutes, watching these lights then i asked mum to come and have a look, buy the time she stood up and looked out my window as she was on the other side of the train, when we looked out the lights where gone.
