I've had a few dreams with ipads, sometimes at a glance, maybe one time I was even using one and browsing apps and such. It looks like ipads don't recieve very much perspectives in the world of dream interpretations. Many dreambooks believe a phone predicts the dreamer gets confused by someone in the waking life. Gustavus Miller spoke somewhat about the old-fashioned telephone: the dreamer's affairs will become uncertain or disrupted by someone. Hasse I think only interpeted a telephone (a message from the unconcious, with the possibility of later facing some old issues). Judging from how the symbolism of devices like phones and telephones were taken in dream interpretation, they all involve a stop of affairs or confusion, the output of others. My guess is an iPad would have oftenly been interpreted as something like, "To dream of an iPad means that the dreamer is not quite satisfied with some events and is longing for the past." "Dreams of a tablet can mean that the dreamer will be introduced to new responsibilities. Now is the time to make the most of your time before such a phase." "An iPad can be seen in a dream by people who fantasize about their dreams. However, some plans can be hindered by the satisfactory of others."
