Here are some symbols that might be universal. They don't always represent the same thing. Sometimes you have to figure it out.
-A car that gets in your way = a block
-Various people = what that person means to you.
-Dogs = a fear you don't need to have
-Green = love
-Running water = cleansing
-A display of white of gold light = the light
-Orange or yellow = willpower
-a kitchen, refrigerator or stove = an energetic system (think about it

)
-people riding on bicycles = energy cycling at a high level
-difficulty operating a computer = difficulty with making a mental connection of some kind
-empty shopping carts = hungry ghosts, earth bound spirits who are hungry for energy
-a bunch of grapes = soul group
-assortments of sweets = what is available in a higher realm
-items of clothing = aspects of self
-cars, houses, boats, planes =can equal one's self
-The people who are found within a car, house, building, boat, plane = aspects of self
-If you drive while sitting in the back seat of a car while somebody else sits in the driver's seat, this person = an aspect you are giving too much control too.
-children = childish aspect of self
-immediate family members = aspects of self
-distant family members = disk members
-a twin you know= aspect of self is being addressed
-Showing up to school on the last day in order to take a test = something you haven't taken care of
-bumping your head= you're doing it to yourself, rather than something from outside
-clothes or other items neatly stored away = you're in balance
-items stored in a messy way = you're not in balance
-an image of recyclables being neatly packed within the containers you place recycled items (plastic bottles etc) in = things within your being are being put into order
-Magazine or newpapper pages flipped through = events in the world
Another thing that will happen is that things that don't seem to be related are placed together, so you can see how they are related. For example, two different parts of a limiting belief system.
There are many more, I can't remember them all now.
