In waking reality, we have seen how some sick people are very self conscious of their looks. They would apply make up and dress up to look better, or at least, to look more normal.

The dream interpretation of dream imagery of sick people applying makeup means they are seriously ill. This in itself, is bad. This dream may have been invented out of your own intuition. You are probably aware of how seriously ill the person was and your gut feeling is that their health condition may not improve. Your intuition is likely to trigger a dream to suggest what you guess may happen.
