Ladder:

General Meaning: Means of passage
In real life, a ladder is a useful tool used when you want to get from a low point to a higher one. Perhaps accessing contents that are stored in the attic, you pull out the ladder. If you dream of a ladder, this is a symbol of traveling and passage, or a change of address. The rungs of the ladder signify progress. If you dream of falling off a ladder, or dream of being on a shaky ladder, you may need assistance in life, otherwise your endeavors will fail.
