A while back I made a post about how I associate colors with numbers. Since then, I have discovered that this is a real thing called Synesthesia.
All this time I thought it was just me being weird. Learning that it was actually a documented neurological phenomenon was really exciting to me.
From what I've read, it's more common with people on the autism spectrum. So I guess that makes it relevant.
I would be interested to hear if any of you also experience, or know someone who experiences Synesthesia.
