Grade
To see your grade in your dream represents how well you are doing in life’s lesson and how your are progressing through each stage in your life. Consider the significance of the letter. Perhaps it refers to someone’s initials.
Lemniscate
To see a lemniscate in your dream symbolises time, longevity or possibilities. If you see objects shaped like a lemniscate, then the dream may be drawing your attention to the number 8. Consider the significance of this number in your waking life.
Masturbation
To dream that you are masturbating represents your unacknowledged and unexpressed sexual needs/desires. It may also indicate you need to take care of yourself in sensual or emotional ways which are not necessarily sexual. Or perhaps, you may need to put forth a little more effort toward some relationship.
Digging
To dream that you are digging indicates that you are working hard to uncover the truth in a problem that is haunting you. You are overly preoccupied with trying to find out something about yourself, your reputation, or your self-identity. Alternatively, the dream suggests that you are trying to get to the root of some issue. Or the dream may be a metaphor to imply an insult.
Compact Disc
To see a compact disc in your dream represents a need for enjoyment or a distraction. It also points to the opportunities and possibilities within your grasp. Consider the type of music and the title of the compact disc. If you are giving away the CD, then you may be trying to convey a message to that person within the songs. Alternatively, the CD is analogous to the meaning of a circle.
