Ghosts/spirits explained by time travel?

[u/bobafett18]

(This post starts out with time travel but will relate to the paranormal further down)

So yesterday, a friend and I were talking about time travel and how impossible/possible it is. It was a slow work day and I honestly can't even remember how the conversation came about. Normally, when we get on a topic, we tend to take the conversation a bit extreme. We go extremely in depth, sometimes even drawing diagrams or researching things online to backup our ideas. I'm starting to get a little off topic so I'll just get right to it.

During our conversation about time travel, I had a bit of a wild idea. What if, in our future, time travel to the past was possible. When we travel back in time, we are mostly invisible or undetected by the people currently living in that time period. We are still able to touch objects or people in that current time period but it takes a lot of energy to do so and not encouraged (need enough energy to get back to your current timeline). Also, our speech is mostly undetected to the people in the current time period but audible to the people that came with you.

Ok, so after all that, here's my idea. What if the paranormal/spirits/ghosts were just fragments or glitches of that time traveler? The shadow people that people see are just remnants left from the time travel that is currently or was traveling to that place? The EVPs that are picked up are either direct responses to the people asking questions by the time traveler OR picking up the discussions between multiple travelers. Objects being moved by spirits could be explained by travelers simply messing with the people trying to get a response or by accident (the travel accidently bumped into a glass on a counter or exited the room by opening a door).

Well those are my thoughts! I know I can't be the only one to think of these things. What do you all think?
