Given that it was a dreamscape, Skisan did not actually need physical contact to get a stronger connection, but he held out a hand for the other to take anyway. It would be a good indication to the other of when the expect his influence.

Only when after the other took his hand would he act to help reinforce this being's sense of self, as it were. He didn't know him well enough to know what that was, but he could help stabilize and allow him to separate himself from the lingering presence of other. Skisan's caution here was primarily wanting to make sure he didn't get tangled up into this person's sense of self. If he hadn't existed on his own in a very long time, it was entirely possible, which meant the best bet was adding as little actual influence of his own as possible.
