Time travel

Yesterday I have watched an interesting teleshow about time travel. One story of a woman-scientist which explored cave and lost her way. A little later she had found another way out and came to a strange village with habitants which look and speach were outdated. She decided that it's a colony of Old Believers and stayed in the house for a night. Next morning she didn't find hosts at home and went to the river where she met her friends which were looking for her... during 2 weeks. She told them about the village and took them there but have seen only basises of the houses. The village really existed in this place... 150 years ago.
Looking for other explanations (besides time travel) I can suppose that the woman had delusion or it was a case of clairvoyance. But where she had been during 2 weeks? Is it possible to have delusion during so long time?

Next guest of teleshow was a hypnotist who sent patients to past and future. But it was hard for them to see their nearest future or detailes of celebrity's murder and other significant events - strange reg light covered everything. They supposed that Time Keepers prevented them to see what they shouldn't and disclose secrets. I believe in it because in case if it were just their imagination and not real time travel they would invent all detailes and tell an interesting story...

But at least one enigma was found out - Amber room is in Kaliningrad region... Who knows, maybe it is true?
