A hotel in a dream often reflects a transitional identity -- who you are between one stage of life and the next, when nothing quite feels permanent yet. Losing your room or wandering unfamiliar hallways can mirror the disorientation of that in-between period, before a new sense of home settles in.
Let the Moon be increasing in light, and free from the aspects of the infortunes, when you would cure sore eyes. - William Lilly (1602.-1681.)
