I'm glad you included this additional meaning of the unicorn. Like so many symbols, they have been co-opted.
The unicorn is also related to the Capricorn journey from duality and the material world, to a singular, spiritual focus. Going inside, focusing on the third eye in meditation, and connecting with universal consciousness.
