Yes 
To dream of 'yes' is simply that, an emphatic 'yes' from the universe. Be sure to check the dream for alternatives in relation to aspects and environment.
Dreaming that you feel terrible emotionally while everyone is saying 'yes' may be implying that there is emotional clearing to be done before proceeding in a positive fashion.
Yesterday 
To dream of yesterday is suggesting that you may be stuck in the past, and it is time to forgive yourself, let go, and move forward powerfully.
There may be a simple thought or lifestyle you are hanging onto. Regardless, to dream of yesterday indicates that now is the time to be strong and move on.
No 
To dream of the word No refers to negative judgement. This judgement may be coming from within yourself or imposed upon you by others. You may be experiencing shame or a strong desire for approval from others.
