Your elevators (like stairs) are interesting to me. I know different levels relate to thought/brain (top level), emotions/sexual energy (lower level/basement), etc. I usually have stairs though and had a dream where I was late for therapy because I was at work (top floor :-) and got a new project that was exciting and I wanted to do that instead of go but I really wanted to go to therapy too (which was in the basement) so I'm running down the stairs and got stopped in the middle by a problem only I could solve -- I had to choose to do the "right"/honest thing and be later to therapy or keep going to therapy so I would not be as late, ignore the situation that had stopped me (the situation was significant in itself, too).

You don't know where to find something you are looking for and eventually get crowded out. Everything is sort of vague though, you start with your family of origin at an amusement park and then set off to join your significant other. Sounds sort of like growing up to me. That it is sort of vague around the edges would indicate to me that it is not an immediate or specific problem (like I had with the late for therapy dream which my therapist and I worked on that week) but more an ongoing/"life" problem; don't know if you have a pleasant or safe childhood, were with "fun" people and felt one of them, etc. and then going off on your own you feel insecure/an impostor (don't know what you are doing, where to find your so, etc.) or, from the other end, are having trouble with finding an appropriate/good so and your childhood looks good in the distance by comparison, you are not fitting in/being crowded out by your more current task.
