In Buddhism, Mara is equivalent to Satan. He is the demonic force who sent all his minions to tempt Buddha from the path of enlightenment.
In Hinduism... The deity of death and destruction, the opposite face of Kama, which is love.
In Anglo Saxxon... Derivative of the word Nightmare (as you said).
I was reminded of maya, which means illusion in esotericism (which really means inner reality, or the real reality), and fits to a cup of tee.
The word totem is derived from the Ojibwe word odoodem, "his kinship group".
Totem poles may recount familiar legends, clan lineages, or notable events. Some poles celebrate cultural beliefs.
in my front yard = As it is outside your house (you), it may mean what is not inside you yet, maybe what you are considering or playing with. I guess it could also mean your public side.
with two of my old teachers = what they taught you or what they represent in you, which is learning.
and my mom was giving us games. = Either your mom or what she represents in you - your learning, guidance, values, etc.
She gave my two old teachers a game, = She gave you some kind of game of learning, that incorporated what those two teachers taught you. So think of their two subjects and relate what your mum, or if not, you, offered you to play or learn in a fun way.
... but she gave me a black case for my ipod nano. I told her that this is just a case, not a game, and I need another one. She told me to just deal with it.
= It sounds like she gave you the "shell" of the game, but you have to invent it. You have to learn. My best guess anyway.
I then look over and there is a greenish-blackish chalkboard that I had written on.
= Again, this equals your lessons. As a teacher uses. Thank God it's the normal colour, and not some wacky symbolic colour I have to interpret and go crazy with.
On the board, I wrote: "I love (with a heart shape) you Mara."
= No matter which interpretation of Mara you pick, there can be no doubt it is the worst thing in the universe. "I love you hate, illusion, destruction... the negative. Daymare." This can only mean it is all you know, at least in this instance. Or you are consumed by it, embraced by it.
and the next line down said, "I've worked so hard but now I'm depressed."
= Which confirms that.
Like many people in this modern world, they work their faces off, and have little love to show for it. Slave labour.
but I didn't write "depressed" instead a picture of a sad face with blue tears was shown.
= Almost like dreams use symbols, maybe the most powerful language. Does a picture say 1000 words? It impacts us much more.
Next to the name Mara there was a face that would be similar to one on a totem pole.
= Or is it because it's the only way to represent the totem? Or maybe just the face next to Mara was the totem. The meaning, that is, in your life that you should have next.
Whatever the totem pole represented, was where we were supposed to go next.
The Totem Pole is a fascinating thing, and even moreso in a dream.
I will stack my non-reputation on that it means the lineage of your consciousness, or journey, probably lessons or main points in your life.
As in your dream the next line down gave the next bit.
The main thing with it is the multi-levels. Just like consciousness and growth and learning is over time.
So that is why it pictured where you should go next.
Then you woke up to that message: Where to go next in life.
The ultimate meaning of your totem is to gain meaning in your life.
Evidence that dreams know a meaning you don't consciously, as in Mara.
