Is Astral Projecting dangerous?

No, it is not.

But in some cases:

We all know astral planes are 7.

But there is a Ground plane inhabited by Lower degree malacious beings.

When our astral body comes out from our Physical body. then it starts to inhabit in the Groud plane of astral world.

Here our astral body may experience some kind of demons or wicked spirits Hidden beings(Djinns, shayateens).

They try to kick our astral body out of the astral world's Ground plane. they also want to have food from our fear. how much we fear that much energy(food) they will get. They generelly don't harm our astral body anymore.

but in some cases these beings surrounds our Astral body and never allow it to return inside physical body. During this time problem will arise in physical world. you wont be able to wake up. untill and unless they(malacious beings) allow our astral body to return into physical world.

it is not fake but a dark reality.

After death every human soul travel towards 7th astral plane in order to hear God's word. this astral world is the world of dead people not living.

we are making fool to our selves but not God.
