Hasn’t there ever been a building, i.e. your own home, a building which is your workplace etc which you are very familiar with navigating around but maybe one night you have had a dream of being in that building and coming across secret rooms or secret corridors leading to secret rooms? Then next time you are in that building for real, you have tried searching for those hidden extra rooms and/or corridors only to be disappointed?
For example, there was a college a friend of mine went to, there was a warehouse style building that had mostly ceilingless corridors and classrooms. He had a dream that he came across an hidden extra corridor, and it lead to some classrooms that he had never seen before. This particular corridor and it’s classrooms appeared to be better decorated and a lot more cleaner than the other corridors and classrooms in the building. The corridor was a gold and light blue striped, (gold at the bottom and light blue at the top). The people in those classrooms were very friendly and offered to be friends with him and some said “we should meet up together sometime, just tell us the time and place and we’ll be there”. At the end of the corridor was a unisex toilet and there was also a shower in the small room containing the toilet as well. The room was decorated with teal green and white tiles and the soap used for washing my hands smelt divine. There was a party going on in one of the classrooms, and the people in there were more than happy to let him join the party, and he was offered the usual stuff you’d expect at a party - coca-cola, booze, (He declined all offers for some reason, although nobody got offended). Needless to say, he told me that he was very impressed by all of this.
In the morning after the dream, he was in that building, and for some stupid reason, he tried searching for the non-existant corridor!
He tried moving one of the lockers to see if the entrance to the corridor was hidden, and he also tried looking in a cleaner’s cupboard that had been left unlocked. Someone in the corridor asked him if he was lost, and he told them about this corridor, and they said that to the best of their knowledge, no such thing exists and that they must have an amazing imagination! Needless to say, he was very disappointed about this.
