Are the Sins in dreams, sins? Background: Recently when I was in the deep sleep I saw some dreams, which showed that I am going against the five precepts. 
For Instance, I lied somebody. I felt that as I lie in real life; I remember that I planned about revealing disinformation and creatively managed the flow of false information.
If it was a real situation I may not act in such way. 

Is this scenario really cause to break the fourth precept?
As we know, dreams are born based on the feelings of our subconscious mind. Therefore, Isn't it my own fault to see such a dream?
According to Buddhism, to do a sin, you have to consciously do something using your body, speech or using sitha.

In a dream you are not doing anything consciously. Therefore simply you can not sin in dreams.
