I feel your pain Only thing I can replicate, is WBTB WILD. But even then they are not identical, in fact, the experiences can differ greatly.

Each time I stumbled into something cool and tried to do it again, something else ended up happening, could not do any of it again the same way, no matter how hard I tried. Some people say, that when you stop trying hard, that's when it happens.

The LDs you got were DILDs or WILDs? Are you practicing any technique? Dream journal? How is your dream recall?
