Who knows about this stuff?

True this!
Yall Nana thought this was bullshit for long time, but it is not.
If you start listening to the right frequecies at night, while you are meditating (yes I said meditating), and learn grounding, you will see many many things in your life change.
You will begin to find your inner connection to God/Source. You will have amazing dreams, you will physically feel better. Positivity returns, you can literally separate your soul from your earthsuit to do wonderfull things. No Nana is not crazy and it doesnt happen over night. You have to work at it.
You will see amazing things.
