Is there an Afterlife?
As an experienced Astral Projector (Someone consciously projects their consciousness outside of their body and leaves it while it's sleeping.) I can 100% with the upmost certainty say that there is indeed a Afterlife.
Whenever I Astral Project it is quite literally my consciousness leaving my physical body and exploring other planes, dimensions, realities and much more. (My body is in like "rest mode" until I return to it). While exploring I've come across many souls and entities, we aren't the only ones in the Universe and it is quite lovely. Though there can be some more spooky areas as well, but you can quite literally just avoid them.

What happens after we die?
That truly depends on the way you died, if it was sudden then you might experience confusion and temporary memory loss. If it was slow and drawn out, then you may be hit with a huge wave of warmth and comfort as your soul leaves your body.
Your soul will basically enter the Astral Realm and you will be either met with loved ones, your Spirit Guides (Some religions call them Angels or other titles), or might even be met by both. They will then give you a moment to adjust and process what just happened. You will then be given time to relax and just chill out for a while before you begin reviewing your life and seeing if you accomplished the things that you set out to do in this life time.
After reviewing everything, if you have more things you need to accomplish then you're given the choice to reincarnate. But if you don't want to yet or just don't want to reincarnate again, then you can find some lovely places on the Astral Plane and explore/relax there.

Personally for me, I've thought about hoping over to "the other side" many times; but I have a reason for being here at this place in time, and reincarnating again for this would be a pain in the ass lol. So it's easier to just stay here and fulfill my purpose.
Also, there's many things that we take for granted here. Such as tasting foods! You can't eat food in the afterlife, but you can recall the sensation of it. You also can't smell things, physically feel things or feel temperature.
That is to say; Yes, while the concept of Death can be terrifying to some, it's nothing to be scared of. Your soul will continue to exist after death and you will still be the same person. There is a After life and there is a "Heaven", but it's more like "The Higher Astral Planes" and it is a place that you can explore while Astral Projecting's, however living beings can only be there for a short amount of time before being recalled back into their physical body.
Angels are real and you can be reunited with any passed loved ones.
Hell is "The Lower Astral Planes" and it's also a state of mind as well. If you live your life mentally torturing yourself then you are basically creating your own hell. So if you die and continue to subject yourself to senseless self torture then you will be taken to The Lower Astral Planes since that is what you are quite literally expecting/manifesting for yourself.
Uhh, so yeah! Live your life knowing that Death isn't the end, but a new beginning; know that you are being protected and guided through life and that we aren't limited to what we physically can see.
