After Life

I have been thinking this for about 3-4 years now but since i am young people will think its a little wierd. Im 17 yo and i have been thinking what happens when you die and i have been curious is there something else some other world or maybe another dimesnion (and no this is not a suicide post).
From all the science forums and shows i have been "collecting" data and gathering information about other Dimensions.
On different ghost hunting shows people are seeing hearing feeling some unnatural stuff happening but what if this is another dimension colliding or grinding with our own trough some sort of electro-magnetic field thus seeing feeling and or hearing people from a parrarel universe/dimension. Do we interpret this as "after life" or is there really something else after you die.
(Google picture dimension)

Some study was testing if people have souls and if souls leave their body after you die. Scientists have put multiple dying people on scales and watched them die. When they died scientist looked at the scale and saw that some weight went "missing" and they have ruled out all the last breaths of the dying patient concluding that humans have souls. (Tell me more in the comments if you know more :D)

My conclusion is that there is no after life but only 2 dimensions or universes grinding colliding at some electro-magnetic fields us experiencing and seeing same people from different dimensions. I still am curious what comes after death if there is something after we die we will never know for sure. Feel free to chat in the comments about this topic with me.
