I had a dream the other night that ants were trying to invade my house.  I could see them coming from the garage in a line trying to make their way into the back door of my house.  I remember blocking their path, and doing whatever I could so they couldn't get in.  Next to the garage was a pond of some sort.  After I thought I'd taken care of the problem, I went into my upstairs bedroom window & could see the ants making a tunnel through the water to get into my house, seems there was no stopping them.  That was all.

Your house represents a mental attitude, one reflecting those opinions and beliefs you are most comfortable with.

The ants being insects, would represent an emotional aspect of your own nature, reflecting a feeling with which you may be bugging or harassing yourself. Ants can reflect a feeling pertaining to being industrious, working on something useful. A great number of ants would imply there is a certain intensity of feeling upon this issue.

Coming from the garage would imply that this industrious feeling comes of a point of view that does protect rational thinking. Because the ants walk in a line, it would indicate that in your mind the feeling of needing to be industrious is quite in order or appropriate. But, this feeling is using an opportunity to enter your way of thinking in a way that is not upfront ? not perfectly legitimate. (trying to make their way into the back door of my house) The scene suggests you can do your best to block this feeling from entering your mind and way of thinking.

The dream suggests that you need to use your highest level of intelligence and look out ? be watchful or careful ? regarding the feeling of needing to be industrious. When using greater intelligence and your personal point of view (my upstairs bedroom window) you can see that this feeling is actually undermining a body of spiritual knowledge or simply spiritual thinking (the ants making a tunnel through the pond water). {Scripture does not say that life is supposed to be all about working. Perhaps when you see this point, this feeling can be stopped.}
