If short, it is from the realization of less volatility than implied.
If long, it is from the realization of more volatility than implied.
Most beginners don't know that this is the cause of the P&L of a option.
Most beginners don't put an emphasis on price. They look at one-dimension of an option, such as time, and go by that, when options are multi-dimensional. Not saying you are or aren't, just putting it out there for your information.
