Sex - sexual dreams are not always about actual sex.
Having sex in a dream may be a straightforward expression of sexual desire. It may be your libido's way of telling you that it's been too long since you have had sex. It may indicate repressed sexual desires and your needs for physical and emotional love.
Alternatively, it may represent the finding of your Self through opening yourself.  A merging of energies, aspects or qualities within yourself, (a psychological completion and the integration of contrasting aspects of the 'Self') Sometimes, they are about how we perceive people and how we think others are perceiving us.

Gay sex (if you are heterosexual) - signifies not necessarily a homosexual desire, but an expression of greater self love and acceptance. Although each of us has some element of homosexuality in us subconsciously, it does not necessarily mean we are gay.
Being played out in a dream could suggest a desire for a father's love (for men)..., or the mother's love (for women). Possibly because that parent wasn't very demonstrative about their love towards you. So you are led to 'crave' the love of another man/woman....as well as curiosity pertaining to homosexuality.
It could be a conflict or anxiety about your own gender or feelings of sexual inadequacy...or your perceived inadequacy in your own gender.
Also, it could represent the act of masturbation. Being ashamed, or feeling guilty, could represent the 'taboo' or ridicule expressed by others about this private act.
Alternately, there could be a quality in the other person you find attractive, and desirable. One that you would find equally attractive in a person of the opposite sex. Aside from the actual 'urge' and stimulation of sex, everyone feels the need to be loved...or feel a connection to another person. The act of sex (making love) is a personal way of expressing and sharing that connection.

Restroom (with a lot of 'holes' like windows) - a restroom is the place for ultimate privacy. Because your dream restroom has large, window-like holes,...and you became angry, suggests you feel you have no privacy, or that your privacy in being intruded upon.

'VIPs' - represents people of importance, or influence, in your life. A teacher, your parents, boss....etc. Because they are coming in to take a look around suggests you feel as though you are being judged, or evaluated somewhere in your life.

Hide/Hiding - suggests the unwillingness to face something, or situation in your waking life. In daily life we hide from things that we don't want to deal with or we hide from danger. Generally, we attempt to hide our own negativity and mistakes. This dream may call for an honest reflection on personal characteristics and an evaluation of how much fear influences our lives and decision-making.

People looking at you - suggests you feel that everyone is watching you, or that you and your actions in your waking life, is 'on display'. Possibly, again, alluding to you feeling a lack of privacy.

Spraying the people and it doesn't affect them - suggests you've expressed your emotions, but you feel like the people you've expressed them to don't care about how you feel.

Hot Water - Water is emotion. Being hot water relates to your feeling angry about something in your waking life. Alternately, it could also suggest you feel guilty, or that you are, or will be, in 'hot water' for something you feel you did, or didn't do.

Put clothes on (covering up) - suggests feeling shy, reclusive, or embarrassed somewhere within your waking life.

Bad phone messages - suggests you feel you are being ridiculed, or talked about behind your back.
