Weird Dream (Recurring every so often)

Ok, so i have this dream every few years which feels so real at the time, in the dream i walk through a hotel in a series of narrow corridors which are quite narrow and no windows, sometimes there is a different parts of the hotel and the odd strange character but not always that i don't talk to just keep walking, its like a secret set of corridors and eventually lead to my apartment which is hidden and is always cosy and warm but does not seem to have windows and is small. the dream is so real at the time that it makes me wonder if this place really exists, the dream usually happens every 2 or 3 years but sometimes longer and always makes me feel like i keep forgetting about my apartment but the apartment is always the same and untouched. any idea of the meaning of this dream? or why its recurring?
