Do you know anyone who has experienced something very unusual

Yup. Me.
My Dad was stone cold deaf and unable to hear voices for my entire childhood, then one day I call home, he answered the phone and knew it was me by my voice, but nobody in my family will discuss the change. I can't stand them at all. It's too odd.

One of my exes had a major head injury and died for a period of time then was bought back to life. He told me about going through a tunnel of light and seeing his deceased aunties and uncles, telling him to go back its not his time yet. Such a profound experience.

Or just being here ! Weird in itself !
