My Dream Interpretation
by myjellybeanIf you dream your rival is wearing lipstick and you aren’t, you may fear she is going to win over you in a romantic situation.
If you dream that you put on lipstick, you are growing confident in your female powers. Putting on lipstick can also mean masking communication, so dreaming of someone else putting on lipstick suggests they may be keeping some information or truth from you.
To dream of buying lipstick at a store is very lucky - the more you buy, the luckier you will be in real life.
