Abscess 
To dream that you have an abscess is an indication that a feeling needs to be communicated.
Pus
To dream of noticing pus symbolizes something that needs to ooze out, perhaps emotions you wish to express. This may relate to pent up emotions such as biases, attitudes, or other bad feelings you have been attempting to release. You need to admit the presence of these emotions, but know how to properly deal with them. Recall on which body part the pus is located as it points to additional clues about your dream.
Mucus
To dream about mucus generally symbolizes something that is burdening you that you may not be willing to vocalize or speak out about right now. This secret or thought is unhealthy for you to hold in, like as we know it is better to spit out mucus than to swallow it back down. Your subconscious is telling you to share your story, secret, or an opinion that you may have about something, since you are currently letting it affect you in a negative way.
Quinsy
To dream that you have quinsy symbolizes an inability to say what you mean.
Alternatively, you may feel that what you say is misunderstood.
