Yes. We are used to thinking that dark matter is somewhere far away and it just plays with the astronomers, but according to the theory dark matter is all around us. The minor issue is: how can we detect something that influences gravity, but cannot be detected with the tools we use.
Mostly we analyse something using some kind of radiation (X, gamma, IR, visible), or chemical interaction or mechanical interaction. But when the matter we are searching for is everywhere how can we use something that is outside it to be able to catch it. Interesting indeed.
