I believe that time travel can be done but you cannot alter it.
In my opinion I believe that Time travel can be done through dreams. I've often had dreams of "past-like" things.
I know it may sound strange but I've also had dreams of random events that have never happened before, I remember it for a small while then about a few weeks later they REALLY happen and I get a dejavous feeling.
I've had this since I was little and I don't know what it just really scares me. I'd like wake up one morning and remember in my dream I'd see me doing something in great detail like I remember everything about it. Then when it really happens I get a flash back of what my dream was and I feel dejavous. It's creepy but after all that I believe time travel can be possible. Just it's hard to obtain the skills to do it, or it's hard to notice it.
