Tiling a floor onto old stone flags/bare earth.

We have an old stone floor, with a few gaps between them, which I believe is laid straight onto the bare earth. I don't want the flags so need to cover it before tiling with large wood effect tiles. Do I put a damp proof membrane down first before a self levelling compound or would you advise putting something down to seal the floor before adding the membrane and SL compound.
