On the first dream... There're many possibilities. It would help if you revealed more about your feelings and history with this teacher. Dreams are often the subconcious worries and feelings emerging from the depths. The white walls are simply placeholders, most likely. White is a very uniform and bland colour, and unless it is completely out of place, it's... not unimportant, but... -thinks- inconsequential. Naturally there are exceptions, of course.
The second dream is mostly a subconcious fear. You are afraid of losing something as precious as the cardigan, since your mum gave it to you. Money also plays into this. It's possible you feel you would attempt to save the money before attempting to save the one thing you, too late, realize is more special. The colour grey is often used to signify depression, unimportance, sullness, gloominess, etc. The fact that a boy from your swimming class is there when no other recognizable person is could have meaning, as well. You may wish to be friends, or even more than friends, with the boy.
The walls represent your life, and the gutter runs out of your life. Anything sucked through and out of the gutter is lost from your life forever.
Of course, this is all speculation. Dreams are complex and hard to understand, and often no one can know if their speculations are true or not. Hoever, I hope this helped a bit.
I reckon your dreams have meanings. Maybe later down the track you'll release the meanings of your dreams. Like Shadowchild mentioned the cardagin your mother gave you might be precious to you, the colours might reflect your moods and the boy and teacher in your dreams could also mean something that now you might not understand but later you might understand what those people mean and why they were a part of your dream. Hope I didn't sound too confusing.
Those are good as ideas VC and ShadowclawFC. Especially about the cardigan and the coins.
This is a really strange dream i had this year. it was just after I recieved the invite PM for the Sneding release party.
Loza was holding me by the wrist and pulling me around corners on the outside of a stone building which was decorated with coloured streamers. Loza was pointing at people and saying stuff that I couldn't hear. then Loza pointed to this man with blonde hair and said "That's Min!". And then I woke up. I was so freaked out I was actually questioning my sanity.
Before this Alxtrov had said something about how I'd accidentally called a female member a guy when I posted(or something) when he PMed me. So I think that might have been an influence.
Another dream I had. I enter a pet shop wich seems to be outdoors because it doesn't have any walls or doors but I think it has a roof. I look up at one of those glass cubicles that have puppies in them. I don't know how but it is above ground. As I am looking through the glass I see that in the box are my pets! My two guinea pigs Nibble and Coco. Next to them is a kitten with aqua-ish fur and teal streaks. Nibble and Coco are sitting down (if you could call it that) and the kitten is stalking around. A man is now walking next to me holding Nibble and Coco as I head towards the place where you can sit with them. The man puts them down in a carpeted area surrounded by large coloured building blocks. The guinea pigs escape and I chase them down the drive way which is now the drive at my house. I catch up with Nibble and pick him up. Coco has stopped in the middle of the drive and as I walk towards him and bend down to pick him up, he shoots from his position and runs down the street. Not holding Nibble anymore I race after him dodging cars that are parked on the side of the street. I can't see him anymore so I return to the drive. In his place is a little hamster with cream, poofy and sticky outy fur. I pick the hamster up and return to the pet shop. I come away again knowing I've bought Nibble and Coco as well as the aqua cat and the little hamster. I realise I've missed school and arrive to see we are going on a bus. The seats are red and black with a hole in the back. They are arranged in curves. I sit down and place a white paper bag across my lap. Apparently it has the animals in it. Once I am seated I realise that there is no driver and there aren't any walls, doors and this time not even a ceiling. The bus 'stops' and I get up seeing teh seats are concreted to the ground. I walk away from the seats and look around. We have arrived at a market. People are standing around cardboard boxes with lollies in them which are on the ground next to what seems to be a lake. My friend comes over and nicks a rasberry lollie from a box and eats it. I pick up one too. As we walk along I notice prices on the boxes of lollies and realise that I've actually stolen something and I don't have the 20cents the lollies costs. Trying not to draw attention to myself I walk away from my friend and along the concrete. I see another of my friends heading towards a stall on the opposite side that is selling a plastic star on a stickn that has flashing lights in it. As she reaches for it my teacher jumps out of nowhere and lands next to her, hands outstretched and says; "Who's stealing?". And then I wake up.
Glad I could help Meza. I'm not sure about these two dreams though, what they mean.
Another dream I remember having (like ages ago):
I'm standing on a coloured rubber playground surface. In front of me are children on climbing frames. Suddenly, I realise I need to go to the toilet. As I walk towards where the loo, which is a battered wooden cubicle, I stop. I remember having been here before so I head to where the loo was last time, in a massive rubix cube that has a flip top on hinges. I walk around and find it. As I open the flip top I see that there is no toilet. Panicing, I race back to the loo where I was before and open the door. Luckily there is a toilet this time. When I am washing my hands I slip and fall onto the wet floor. I get up and see that my jeans are wet. I groan knowing that I probably stink, and step out of the cubicle. I return to the playground surface where I was before and hear a car horn beep. I turn and see my mother waving wildly at me through the window of an unfamilliar silver car. I jog over and she explains quickly that I have to go to a meeting with the school principle imediately and that I don't have time to dawdle. It sinks in that I won't have time to change and will have to meet the principle in my wet and putrid smelling jeans. I hop into the car feeling miserable. Before I wake up I see the car from the outside driving down the street.
This was only short but as I was waking from sleep I could see from the eyes of someone falling head first down blue-stone stairs in a turret like building. I'm not sure whether it was a dream though. But what could it be if it was not?
