Self
There are two perspectives to the self in dreams, interacting as the self or observing the self as standing outside. I haven't noticed either one being any less important than the other though the planes and context of the dream itself can be very different from each other.

Actor
The actor/actress in dreams means persona and can be directed to the mask self. Generally they mean things like sociability, outgoingness, creative venue, adaptability, hidden strengths, potentials and weaknesses. The muse. Performance. All the world is a stage. Don't break a leg. A cast of characters. On the negative side the actor can mean shadow and trickster, forms of deception.

Villain
Represents shadow self, warnings of danger, weaknesses, fears, anxieties and insecurity.

Family/Friends
These dreams can be about you or your actual relatives/friends and some of the aspects of their relationship with you, or be symbolic of a universal relationship with community and spiritual, religious being. The male and female sides are aspects of your masculine or feminine side either in ego sense or spiritual sense. The masculine represents sky and sun. The feminine represents earth, the moon and stars. The meanings of your family/friends in dreams will be as different from any one elses as their relationship with such as their own mother or father.

Family and friends can bring out the best in you, or the worst but generally are your closest guardians. A family member or friend may appear in a dream simply because they are protective and provide a sense of security and safety and wouldn't let anyone else harm you. In opposites if they are taking on a villainous role or are an object of jealousy, anger, fear or insecurity they can be representing shadow self as a vent and need for recognition of these emotions.

Uncle
A connection to your own heritage. The uncle can be a substitute father. Crying uncle. Monkey's uncle. Uncle Sam. Bob's your uncle.
Aunt
A connection to your own heritage. Perhaps an industrious part of yourself, aspects you like or dislike. The aunt can be a substitute mother. Ant

Brother/Sister
Brotherhood. "Big brother" in slang towards federal, governmental control/spying.
Sisterhood. 13 Moons. The three sister stars.

Cousin
Your cousin can be a 'next in line' representative of the brother/sister relationship. The children of aunt and uncle. Aspect that is somewhat familiar.

Daughter/Son
Feminine/masculine child aspect. Maternal bond.

Father
Patriarchal. Paternal bond. Creator. God. Father sky. Father time.
Mother
Matriarchal. Maternal bond. Creation. Goddess. Mother earth. Mother nature.

Grandfather/Grandmother
The Elders. Time, age, wisdom, caring, storytelling, honor. Maturity.

All our senses can bear meaning in mind, body and spirit.

Taste/Smell
One of the higher forms of smell is sensitivity to such as detection of  some spiritual presence by an unexplainable production of smell such as whisteria, roses or lilacs. Taste and smell are very closely related and in dreams they can manifest as colors, foods and items associated to the same taste/smell from memory. 'The fruit of the gods'. Honey, nectar. Insence, frankincense and murh, sage and cedar are some of the most common direct taste/smells to the spiritual. Something as simple as a bad or good taste in your mouth can bring you dreams of smells, colors, foods, animals, places and so forth you associate to it.

In some cases the taste in your mouth can relate in dreams to physical and emotional conditions and causes. People who have fainting spells and in some cases migraines often 'smell dust' before it occurs. It is also said that bad breath can be brought on by negative thinking and low esteem. People themselves smell very different from each other by estrogen, testosterone, the use of perfumes, deodorants and some medications like menthols, breath, age, race, location, social order, work place and physical condition. Even many illnesses and infections have very distinctive smells. Some working dogs are used to 'sniff out' cancer in patience. Some working dogs also can detect when their master is about to have a seasure which could possibly be related to their keen sense of smell and sensitivity to the different changes of smell on the human body. Nature uses smell and taste for attraction and repulsion.

Opposites: He/she's like a bad taste in my mouth. Sweet as pie. Take the cake. Honey pot. What's eating at you? Something's fishy. I smell a rat. Ripe. Tastes/smells like heaven.

Touch
Some of the higher forms of touch are emphatic, the ability to sense feelings and energies, 'sympathy pain', those able to see an illness in the body and energy transfer such as empowering an empty item with energies from the self by touch, also taken in forms such as 'hands on' healing or reiki. Also some psychics with a gift of sight use touch of an item to see.

The sense of touch includes such as feeling texture, pleasure or pain and can cover a very broad scale in dreams of the physical body, including physical withdrawal/addiction. In dreams emotional states can also be represented physically such as 'weak in the knees', 'butterflies in the stomach', 'flying high', 'stabbed/shot'. Thought, emotion and the physical body are very integral to each other. If you think this, you will feel that and then your body will respond such as the pulse rate, physical tension and your gestures and facial expressions will change accordingly.

See
Some of the higher forms of see is clairvoyance, remote viewing, having a vision and 'having the sight'.

Sea

Hear
The higher form of hear is clairaudience.
