One practical way to do this is to look at other people and ask yourself if you are really seeing them of just your thought about them. Sometimes our thoughts act like dream glasses. When we have them on, we see dream children, dream husband, dream wife, dream ob, dream colleagues, dream partners, dream friends. We can live in a dream present for a dream future...But if we take off the glasses, maybe, just maybe, we might see a little more accurately what is actually here.
