Re: What can trigger an OBE when you are....
IMHO, living a truly devoted, detached life of service to humanity, love for all, sincerely seeking, sincere prayer, reading & meditating on the sacred Writings (but not to the point of boredom), obeying the holy laws, sacrificing selfish inclinations, limited ways of thinking, & transitory desires for love of God... Striving for a truly God-devoted life awakens the spiritual awareness naturally, even if one's not trying to awaken anything.
No man is a true believer unless he lives in both worlds. There are many impostors. Do not be mislead by the fallen stars. In these end times, the stars are fallen from the heavens, even the heavens itself have passed away, and the new sun has dawned, but the people are asleep, and the thief in the night has come & gone, while so few have risen, with open eyes.
Good luck
