I seem to have quite a bit of "premonition dreams".
Just yesterday I dreamed that I was taking a nap in my bed when my sister comes in and wakes me up to ask if the new dress she is wearing looks good and what shoes to wear with it.
Then she goes to get something from her room and I sit up and put my robe on.
Right after I had this dream my sister came in and woke me up to ask if the dress/outfit she was wearing looked good and which shoes would be best. The only thing that differed was what the dress looked like!
Usually the deja-vu doesn't happen right away, its usually months or even a longer before I'll experience deja-vu.
I just think its really cool and I wish we knew more about this kind of thing happening to people.
