I remember having had short, uncontrolled OBE's in my life before, and waking up in the vibrational state often. However, I never successfully left my body on purpose, especially when trying to manually induce. If I wake up in the state at 4 AM, I always try to resist it instead of "surrendering" to the pull. If I try to induce the experience fully manually, e.g. sitting in a comfortable chair during the day and/or in bed shortly after bedtime, staring at the edge of my wardrobe, trying to "pull on a rope", I can induce a strange vibration feeling in my head and a feeling of pressure between my brows that comes with blurring of the vision but can not successfully even partially leave my body.
Are there any tips? Is anybody here an experienced astral traveller?
