Fear of the unknown is a problem, It sounds like "There is something I should know that I don't know" and it ends up giving you Nightmares only the culprit never shows his face like a eerie misty feeling created by you and revealed in your dreams. You dont need a Religion you just need to know yourself, When you Critise yourself something in the pit of your stomach disagrees with you and hence bad feeling. Say something good in the pit of your stomach it feels good it agrees.Say something mean about someone for no reason you feel bad at your core unless your disconnected from yourself. I know your not afraid of hell or helios the Sun really hot cooking up this earth. Manmade gods are egotistical and need your energy so keep sending up praise. You would not exist without The Source being apart of you, Lol I told myself I was not gonna do this one, Id have to get deeper and Im sure you are connected with non manmade God inside you hence no fear.

In this illusion, body death is just like changing clothing. ...
Under your ego thinking, is your true self, that deep love, that spirt that has no fear of death only spiritual life.

Be at peace...with body life, as nothing to fear in the no-thing of nothing.

Self preservation is kinda a build in instinct

Lol...... talk about borrowing trouble.
