Here's an idea, what if when you travel back in time, you don't magically make a copy of yourself out of nowhere. You and the time machine simply move in reverse time, everything playing backwards as if cause and effect were reversed. However everything and everyone you interacted with start doing different things as you are no longer interacting with them. Once you step out of the time machine you arrive in a different past, the same way the future can be changed by small events(the butterfly effect).

For example if you drop a pebble in a pond then walk into the time machine and go back in time. The pebble would rise out of the water where your hand was, but since your hand is no longer there it will simply fall back. Now step out of the time machine(time moving forward again). Now once again you will see the pebble rise into the air, and unless you grab it, will fall back down again.

Another example is building a log cabin in the woods far from everyone else. After building it you go back in time to maybe even years before you built it. When you come back to the log cabin, you will see it standing there and very likely aged, some strange stuff probably happened to the trees you chopped down too.

Last example is you have a conversation with someone you know, maybe have the same conversation or interaction multiple times within a given time frame. Then travel back in time before you ever had those conversations, chances are the person will remember those conversations even though they take place in his future, that or he will have some strange Mandela effect or precognitive dream about it.

Thought this would be an interesting way to think of backwards time travel, solving paradoxes yet creating some interesting effects possibly dire some effects. Imagine going back in time before someone you were close with died, only to find out they magically disappeared one day when they shouldn't have.
