any reference point
"Any reference point is like a house full of memories. These houses are built from our very first experience. You've said Christmas Day so you can see the foundations of this house are Jingle Bells being sung by her mother to her as a baby; playing with wrapping paper covered in reindeer as a toddler; and thousands upon thousands of bricks laid ever since."
I think this is what your are looking for.
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
