Yes, of course it may have been a few last "sputters" of REM before it finally finished. That's quite cool, though! I have had so few DEILDs work that when they do it's always a massively fun experience, that it's hard to stay calm in order to keep the dream. When conditions are just right, you can just keep chaining, and it's an amazing experience. Catching multiple FAs in a row is also really fun.
