A large, cloud-like thought bubble, as used in comics to indicate a character's thoughts. May also be used to represent a dream or daydream.

Generally depicted as a white or pale bubble accompanied by one or more smaller trailing circles. 

Not to be confused with 💬 Speech Balloon, which represents spoken rather than unspoken words or thoughts.

Many platforms, including Google, Samsung, and Microsoft, previously used thick black outlines around their thought bubbles. OpenMoji's design previously had its trailing bubbles extending from the right instead of the left.

Thought Balloon was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
