Angela, it is very helpful to journal your dreams, daily. I started doing it years ago, and it helps with picking up recurring themes, problem solving, or just generally taking your mental "temperature", so to speak. LOVE your pay phone dream-it is incredible! I think you are highly psychic, and could really benefit from some insight and training to hone your skills, and become more aware, in waking time, not just dream time. (I think this about Georgie and Emily too! Creative people are highly sensitive to vibrations that most people are ignorant of; it helps us think outside the box, and explore our world in a more colorful way).
A train station (or bus terminal, airport terminal) is a place where the living can meet the dead, to carry messages to each other. I have often met my grandmother in a train station, in dreams. A phone is quite literally, the mode to speak with the dead. So, I believe that you did cross a portal, to one level of the other side, where there was much joy and celebration. Everyone was so happy to have this chance to educate you about the "band"-which would be a special group of people. The acronym is odd, but may have some deeper meaning just for you. Often in dreams, odd words will have great meaning, but it is not literal; sort of a "sounds like TITS", like when you play a game. You should meditate on that, as it is probably significant.
As you can see, I am very enthusiastic about dream interpretation! It is a great window into our souls, and so helpful in daily life. When I have time, I will post an incredible dream I had recently....in the meantime, keep track of your dreams, all of you!
