birthday co incidence

my father died in December 1999. prior to his death he was a lorry driver and often used to drive with our pet basset hound in the cab with him. in the year 2000 which was the first year after he died on the day that would have been his birthday 10 th july I arrived outside my place of work and there was a lorry similar to but not exactly the same as the one he used to drive and it there was a basset hound in the passenger seat. the basset hound was the same colour as our pet basset hound. while I was on the phone that day I took a phone call from the company he used to work for .the company had stopped dealing with us several years before and this was the first phone call we had had from them for several years. there were several other small coincidences that year to do with my father( members of the family winning premium bonds only on birthdays, which never happened again ) . I cant remember the full details. but ever since then we have not had any coincidences to do with him . so by coincidence all the coincidences only happened in the year after his death. what I would say is the death of someone does make you more aware of things that happen and possibly after people die you are looking out for a sign from them.
