Powder
To dream that you are powdering your face indicates that there is some flaw or mistake that you are trying to cover up.
Peppermint
To smell or taste peppermint in your dream suggests that you are feeling calm, soothed and relaxed. Some aspect of your life is having a soothing effect on you. You are undergoing a positive change. On the other hand, the dream could be saying that you need to be more calm. Don’t get too wound up over minor issues. Consider your own personal associations with this smell and how a waking situation may have triggered these same associations.
Periscope
To see or use a periscope in your dream indicates that you need to rise above your current situation in order to get a better perspective on things. Sometimes you need to take yourself out of the situation so you can gain a different view. Alternatively, the dream suggests that you need to stop being so linear in your thinking.
Perspective
To have a dream where your perspective changes from the first person to the third person means that you need to take other people’s point of view into consideration. Perhaps you are being too self-centered.
