Correct and weighty. Slightly more 'departed spirit' than English 'soul'.

What a Japanese person actually thinks
Serious, a little supernatural. It's the character in 魂が抜ける ('the soul leaving the body' — being stunned) and in a lot of ghost stories.

Meaning

Literally: cloud + demon/spirit
Actually: The soul or spirit. Leans toward the spirit that survives a person — closer to 'shade' than to 'inner self'.
