Hi empty_spaces.
Im of the opinion that these OBE’s are a kind of LD’s. Having had many of them myself, I developped a technique to induce them, you can find it here. perhaps it can help you to OBE too 
. A final word of advice, if you get stuck, it is most likely that this happens again because somehow, consciously or subconsciously, you expect to be stuck again.
Good luck!
