I have had several experiences, but there are 3 that really stand out from the rest. The first one, I was 19 and I dreamt that I was on my way to work when a car came tearing round the corner at a busy junction that I had to cross and ploughed into me, it really shook me up, for months afterwards I would hesitate before crossing when I reached that junction, then one day I overslept and feared that I would be late for work, when I reached that junction, I was just about to step onto the road to cross it when I heard someone shout my name from behind me, I turned but I couldn't see anyone so I turned back towards the road ready to cross, again I heard someone call my name, but nobody there, then it happened a third time, as I turned back towards the road after the third time, a car, exactly like the one in my dream months earlier, came tearing round the corner, someone was definitely looking after me that day.
The second one, I was 22, I had gone to bed early as I wasn't feeling well, then at 10pm i was jolted awake, and according to my Boyfriend, I sat bolt upright in bed staring at the bottom of the bed, he then asked me what was wrong, I told him that I had just seen my Grandad standing at the bottom of the bed, and that he had said "I've just come to say Goodbye", and then he had vanished, my Grandad lived over 300 miles away, my Boyfriend told me not to worry about it, and that it must have just been a very vivid dream, 2 days later, my Cousin knocked on my door, and before he could say anything I said "Grandad's dead isn't he?", he then confirmed that my Grandad had died at the exact moment that I had seen him standing at the bottom of my bed, my Boyfriend was so freaked out by this that he dumped me for "Being a Witch".
And the third one is closely related to the last one, after finding out that my Grandad had died I travelled the 300 miles so that I could attend his Funeral, and was staying at my Mother's house, on the morning of the Funeral, my 6 year old Nephew, who thought that he was simply "Visiting Grandma" and didn't know that my Grandad had died, came down the stairs, picked up the Newspaper that my Mother always had delivered, and started to head back upstairs, my Mother asked him "Where are you going with that Newspaper?", he said "Grandad wants it", my Mother said "But Grandad's not here", my Dad worked abroad and hadn't been able to make it home in time for the Funeral, my Nephew then said "Not big Grandad, little Grandad", (my Nephew always called my Grandad "little Grandad"), my Mother then asked "Where is little Grandad?" and my Nephew said "He's sitting on the end of your bed and he asked me to bring him the Newspaper".
