Wakinyan
Wakíŋyaŋ is a Lakota word for "thunder." It also may be a portmanteau word which assiociates "wahka" and "kinyan".
The word is usually translated as "Thunder Spirits", "Thunder Beings," or "Thunder Birds". Heyokas, that is contrarians, dream of Wakinyan and can burn cedar to protect themselves from thunder and lightning, since Wakinyan respects and will not harm that tree.
