I don't know personally. However you guys keep saying to Slip about de ja vu, but he is talking about premonitions. For example there was something on the news years ago about a women who had requested her husband not go into work because she had seen something bad happen in her dreams. Later that day the building that her husband worked in collapsed, that's not de ja vu.

Something similar happened with my Great Grandmother. One night she woke up disorientated, and she had large patches of grey come through in her hair. She felt very uneasy and had a vague memory of her dream, it was about her brother. The next morning she received a call telling her that her brother had been shot dead.
