Hi chrwe and Welcome!
Experience is the most helpful, but ideas that contradict one's goals can keep one from reaching those goals -- even when we're not aware of the contradictory ideas! You may have plenty of ideas that are contrary to afterlife experience
For the sake of this one goal of visiting the afterlife, could you do a brief experiment under conditions that are conducive to success?
First, set a time when you will be uninterrupted, well rested, and nutritionally well-'charged.' (I see now that you've been on this site for the last eleven hours, so I wonder whether you'll find a time soon when you are well rested, but later perhaps
)
Next, try sweeping away all your contradictory ideas with a broad statement to yourself, such as "I am setting aside
my disbelief and all I was taught in the past that
negates afterlife experience. I need to have an
afterlife experience. I am not fearful and I am ready. "
You are attempting to clear a lifetime paradigm with this small affirmation. It won't affect your knowledge later; it won't empty your brain's contents, just set it aside.
As you restfully wait for signs of your self trying to comply with the above stated goal, you might hear yourself mentally saying "... but this will never work." or some such. If you do, you have to repeat your request and affirmation that having the afterlife experience is your priority goal.
Stay quietly aware of what sensations or even sense of change that you experience. Give it a half hour of non-contradictory ideas. Please let us know what happens.
I was fortunate to be able to move into the afterlife relatively easily but sometimes when I try to go back I find I am blocked and I have to clear my way again with a process similiar to what I'm suggesting. I wish you much success in this!
Bets
