Can you explain to me how time is regarded as the 4th dimension? Does it mean that if we assume time as a dimension then an object traveling to different time period is possible?

Here’s how I think of it:
Think of an empty room with just one chair. You or I can sit in that chair (location in space) just not at the same time.
If you’re sat in it, I can’t. If I’m sat in it, you can’t. We can both occupy the same chair (space), just not at the same time.
