A question from the dunce in the corner: is dark matter the same as anti matter?
Nope.
Nope.
Nope. Dark matter is a rather 'exotic' type of matter that has been proposed to explain (among other things) the fact that galaxies 'weigh' a heck of a lot more than they should if we take into account all the matter that we can observe. Dark matter may also have some repellant properties (I can see the jokes coming on this), due to the observation that the universe's expansion appears to be accelerating.
Antimatter is fairly straightforward stuff compared to 'dark matter'. We can produce small quantities (small being a tiny, tiny, tiny, tiny microscopic speck) of antimatter in particle accelerators. To the best of my knowledge, dark matter has never actually been observed.
