Needing to pee and being unable to find a bathroom usually means that you're having an issue in life where you're unable to, or are finding it difficult to, express your basic needs. OR, you really need to pee and it's bled over into your dreams. Don't pee in your dreams, just in case.
Being chased often means you're feeling threatened by something in your waking life. It's also one of the most common dreams across all cultures.
Falling is considered by some to be a "red flag from your subconscious." It means you're stressed. It's common with people having a major life problem in some area, such as work or a close personal relationship. Take some time for self-care, okay? Treat Yo Self.
Being trapped - unable to open a seat belt, being a room with a locked door, etc, often means you need to make a change of some kind, like a new job or ending a cruddy relationship. You could just need a vacation to reset your mind.
Murdering or killing someone in your dreams means you're a sociopath. Just kidding, that's not even what it means a little bit. It usually just means you desire to kill off part of yourself - maybe a bad habit or attitude. Actually killing someone, very bad. Dreaming about killing someone, means your subconscious wants you to be better. Dreams are weird, man.

Dreaming of dark looming figures means that you have doubts about the future and yourself. Undefined dark figures can symbolize these worries, and it can sometimes help to try and work through what's worrying you when you're awake. Or cast a Patronus charm.
There's a kind of reoccurring dream that only Type A or perfectionist people tend to have - Test Taking. Specifically, stressful test taking. These dreams remind a person to stay alert in stressful or high pressure situations, like work...because it's not like you need to rest while you're sleeping.

Dreaming of being in a relationship, or of being with a lover actually symbolizes your relationship with yourself. Note that this is separate from dreaming about sex.
Dreaming that your spouse is cheating doesn't actually indicate they're cheating. It's not a "sign." It's not your subconscious tying together "clues." It usually just means they're focusing a lot of time and energy on something that isn't you and doesn't involve you, and you're a bit jealous. It could, sometimes, mean that you don't trust them as well.
Dreaming about a baby usually happens when there's something new coming into your life, or you're expecting a big change. Babies in dreams represent new possibilities.
Dreaming about cats tends to be dependent on your relationship with cats. Cats are independent, free spirits, so they could represent things like free spirit, femininity, creativity, and power. On the flip side, they could also be a bad omen. Basically, the interpretation of cats in a dream is quite open to interpretation, depending on the person.
Vampires can symbolize a few different things. If you dream about a specific person being a vampire, it could mean that you know deep down that that person isn't good for you. Vampires in general can either represent fear and death or sexuality. Dreaming about sparkly vampires means you read low-quality teen literature.
Dreaming about sex tends to be pretty straightforward. It usually means you want sex. If it's very specific weird sex, it can men a whole other host of things. But just in general? You're probably just, uh, lonely.
Things like radios and television can actually sometimes be a link between your conscious and unconscious mind. It is suggested that if you are lucid dreaming, you ask the radios or tv's a question.
Being late or lost can mean that you have little faith in yourself - your timekeeping skills, and your ability to get things completed. Or you're at a very boring party and just saw a rabbit in a waistcoat. A or B. Making a daily to-do list - a reasonable one - and checking it off, or practicing better time-management skills can make you feel less anxious about these things. Also, you should never follow rabbits you don't know down holes.
Snakes, like cats, can be open to interpretation depending on your relationship with them. Many people are afraid of snakes, and since snakes are unpredictable and strike without warning, they may represent things that are out of the dreamer's control, like opening the Chamber of Secrets because a horcrux possessed your body.
Hair is considered to have to ties to sexuality, so hair loss in a dream can sometimes symbolize a drop in sexual desire, where as full, shiny, glamorous hair can mean the opposite.

Dreams about food depend on the kind of food being eaten: Apples symbolize knowledge, for example. Almonds success, and dreaming about ham means that you need to reserve your energy. Unless it's a ham sandwich...because a sandwich can indicate that you're being put under pressure. Or it could literally just be a sandwich. Dreaming of strawberries is indicative of sensual desires.
Dreaming about water is pretty common and is also a pretty telling dream. It's a mirror of how your subconscious is feeling. Is it angry storm water? Clear and warm? Fog covered? Dirty? Full of sea monsters? Are you drowning in it? Yeah...just take the hint.
