Is Near death experience in enlightenment true? I have been meditating intensively according to the Advaita tradition where self inquiry is practiced till realizing that I and effort are just feelings and that the watcher of even identity is the true self which isn't a phenomena that manifests.

2 days ago I had what I felt as a near death experience ,or maybe a great death of the ego ,at night I suddenly had an awakening in trance where there was a clear seeing of the "I" that I thought was  me,then I woke up with a vibration feeling in my head and after lying on my back I suddenly felt as if a light was going to replace me as the identity of the body and me that I thought was my identity all my life was just an idea that was going to be replaced by that light ,I couldn't accept that happening and chose to stay as myself, and I actually cried cause I felt that I was going to die, not realizing that this "I" was more intimate that expected .

Is this a paranormal experience or is it actually how enlightenment should occur ?
I believe such peculiar experiences may be significant, or may not; but in Buddhism one shouldn't cling to them. Enlightenment would involve an understanding of the three marks of existence: impermanence, no-self, and suffering. I mean, if you delve into that experience and gain enlightenment, good! But if you do so and then everything remains exactly the same, you might be discouraged. Just do not cling to the whole phenomenon.
