Congratulations, turbulenceadams! I like the fact that you felt the bed springs. I want to try that too! Hehehe! By the way, there are techniques that you can do to prolong the experience. Also, just because you return to the body, it doesn't mean it's all over. Remain still and re-separate! You can have multiple OOBEs in one night.

As for energy work, I don't use it and I manage to have loads of experiences. I guess if energy work helps some people so be it but I feel that you don't really need it.
