Lies which are often represented in dreams as snakes, Forked tongue, long tails (tales) can point to either lies that people are telling about you, or untruths that you have believed and accepted about yourself.

Correct, also the type of snake or color of snake or size of the snake can also be important in a dream as well.

For example constrictor snakes and venomous snakes are different symbology and different types of lies and different types of attacks of the enemy. One attempts to squeeze the life out of you, while the other uses it's bite to disable you.
