If you see an unnaturally large cockroach in a dream, then you are disturbed by some thought, you can not get rid of. In fact, you have nothing to fear. The dream in which you are trying to etch cockroaches, but on the contrary becomes more and more, means that due to certain circumstances you will have more worries and responsibilities, but you will not be too upset, as they will bring you satisfaction. If you dreamed that you enter a dark room, turn on the light and see cockroaches running in different directions, then in real life you need to give up doubtful pleasures for your own good.
