Hi Sam, thank you for sharing this. It's fascinating!

. One thing I can relate to is the 'fence' idea that cordons us off from ultimately entering the spirit world - I 'get' that! (From my own dream experiences where dead loved ones went beyond a barrier, eg. turnstile, water etc, and I couldn't cross.)
I think it's only natural that even if you sense the nearness of the spiritual world, you will experience fear, and draw back. No one wants to die and leave their loved ones here. After all, anything else is a journey into the unknown.
Nevertheless you say
[The beauty is stunning.
Did you get to experience this only after your NDE - or can anyone? Is meditation the way?
