The Perfect Name

Last night I dreamt that I was hanging out with a friend who I've known forever and I found out that what I've been calling her for the past 13 years isn't actually her real name. As it turns out her real name is the coolest name I've ever heard and way cooler than what she goes by in real life (no offense anonymous friend). Anyway I decided to adopt the name for myself since I've been searching for a new name for as long as I can remember and besides she wasn't going to use it. It was the perfect name for me too, and I have no idea what it was.
...something that starts with an E ... maybe
People always say that kind of thing and they're usually wrong.
"what's that word?... it starts with a P...pahhh??...pedimmmrrr?.. Oh! I know, Harlequin."
