Heirloom Dreams
It's a longstanding Orlendian tradition to record your strangest, most vivid dreams in a journal. It's meant to help cleanse your mind by putting your thoughts on paper so it isn't distracting you all day.
The most outstanding dreams of a family member's dream journal are painted, and kept as a recording of their memory, which is then passed down through the family. Paintings are only the size of a postcard so that they are easier to document, cheap, and transportable.
Some families have a dream album, others prefer to keep their grandparent's dreams in the front pocket of their jacket.
From the name I have expected this to be some magical dream that recurs throughout a family line.
