Hi Tristan,
Dreams that stay on one's mind, especially after years have passed, usually have a lot of significance to the dreamer. Interpretation can be difficult for anyone other than the dreamer and you have given very little detail here. It could be helpful for you to write down all details of the dream and also to remember your frame of mind at the time of the dream such as, what was happening in your life at that time, what were your relationships like, what were you seeking, studying, worrying about, etc. Were there any physical manifestations relating to the dream after waking up such as, dizziness, foggy mind, etc? Answering these questions to yourself, perhaps in a journal, can be enlightening. Sometimes if I ask my Higher Self to give me the interpretation, I will have another similar dream in more detail. I helps to meditate on it before falling asleep. It is good to keep a pencil and notepad near the bed to write down all details while they are fresh in the mind. Sorry I couldn't be more helpful.
