Time Travel Options

Hello
Does time travel exist and is it actually possible? to go back and forth in time?
I await any replies,
Thank you

I would say yes, it is possible. But, from what I understand only through O.B.E (out of body experience). I've actually moved forward a couple hours at one point. I had gone to bed with my husband in a guest room at a friends house. While I was trying to fall asleep I was thinking of something (at this point I'm not sure what it was or if it was anything important) and I don't even remember falling asleep or if I even did. I sat up and looked at the digital clock and it had said 3:14. I felt completely conscious and in control of my body and it didn't even cross my mind that I might have been asleep or outside my body. I looked down at my husband (who was asleep) and then back at the clock and 'knew' that THAT was NOT the correct time. I laid back down completely confused and there was a small moment of blackness to where I don't even remember what happened (this 'blackness' or 'void' came and went so quickly it almost didn't even register in my mind) and then I sat back up again and looked at the clock which said 12:10.

Needless to say I was a little freaked out at first. But, after following up on it through reading a couple books, time travel through O.B.E. is completely possible.
