Wet sleeves mean that the sleeves seal the cooling system off from the rest of the engine so if you have a bad sleeve seal or a cracked sleeve you have water in the oil and that is a big problem

The inside surface of the sleeve is the cylinder in which the piston travels (true of wet and dry sleeves).

With a wet, sleeve, the outside surface of the sleeve is in direct contact with tthe colant flowing around it. The seals for the water jacket in such a case are typically an o-ring where each sleeve passes between the water jacket and the lower (oil) part of the crankcase, and pressure from the head gasket where the top of the sleeve nests closely into a recess in the top of the head.

A dry sleeve engine, the sleeve fits closely into another "sleeve" that is part of the crankcase itself. In that case the outside of the sleeve in which the piston travesl is therefore dry -- the outside of the other "sleeve" (the one that is part of the crankcase) is in contact with the coolant.
