Have you seen the Marvel movie, Dr. Strange? If you are familiar with near-death, out-of-body experiences, and astral projection you might have noticed some very interesting topics and events within the movie.
At multiple moments in the movie Dr. Strange gains awareness of the Astral dimension and learns to interact with the dimension using mental powers. The startling aspect of the scene is how accurately they depict the experience based off of real stories of astral projection.

Here is an explanation from Marvel on the Astral dimension and its characteristics:
When Stephen Strange was injured as a result of his conflict at the New York Sanctum, he stumbled through a portal into the Metro-General Hospital. There, Strange left his physical form by simultaneously assuming the astral form and entering the Astral Dimension, rendering his body unconscious. During this time, he helped Christine Palmer perform surgery on him by re-emerging in the regular universe in his astral form. Palmer was shocked by this stunt and assumed Strange was dead at first. However, he was followed by the astral form of Lucian, one of the enemies he had just overcome.

They battled it out in the Astral Dimension, and some of their actions had weak and muffled effects on the regular dimension. The teacher was able to energize Strange’s astral form and project it outside of his body. Strange realized he could use that power while in the Astral Dimension.

In Marvel, the Astral Plane is the realm of minds. Telepaths are able to access the Astral Plane by projecting their mind onto this realm, more commonly known as Astral Projecting, thus also allowing them to enter the minds of others.

Doctor Strange first practiced astral projection in the Marvel universe in 1963.

Your physical body vibrates at a certain density, a lower density than your energetic or astral body. So your physical body is fully capable of grasping a cup, opening a door, and walking around for example, because those objects are on the same plane as your physical body. Your astral body is energy without physical form and is roaming around on a different plane. Just as in your physical body you cannot “touch” anything on the astral plane, so too on the astral plane you cannot “touch” anything on the physical plane. In other words, you have to be in the same frequency with the plane you want to alter.
