Onerial
Oneirial is a dreamlike or dream-associated xenogender. It can be unbound, full of mystery and possibly, perhaps secrets and spirituality, or incomprehensible but meaningful, hazy but understood, or deep and infinite and mythical. It is sometimes haunting and unsettling like a nightmare, and sometimes pleasant and whimsical like daydream.
History
