This question up until recently was bothering me.
Einstein considered time to be the fourth dimension. However, he thought of it as something unlike spatial dimensions. Creating what we know now as spacetime. Einstein also suggested that the distinction between past, present, and future is merely a
"stubbornly persistent illusion"
However, after listening to Ron Mallet, he gave me some insight that I had not considered.
He was describing the conditions surrounding a Kerr black hole, or a rotating black hole.
He said that it was like the space around the black hole was tea in a cup, and the rotating black hole was like a spoon that was swirling and mixing time space. The tea would fold back onto itself. So, if someone were caught in the current, they too could go back where their journey had begun.
That implied that time essentially was actually
much like spatial dimensions, but you would need specific conditions to be able to move around in time the same way we move around in space.
Or, in other words, I don't believe in the arrow of time.
