When I was a kid I believed that all matter is just energy condensed to a slow vibration - that we are all one consciousness experiencing itself subjectively. There is no such thing as death ; life is only a dream ...... we are the imagination of ourselves.
Or at least, I wish I did. Oh, my mother told me that once, when I was very young, I held the firm belief that it was not I that would move out of home, but her and my dad.
