My dad passed away about 6 years ago, many family members have said that they have felt him, dreamt about him, received signs from him. I have not, is there anything I can do to encourage contact, no one believes he has crossed over. Thanks for any ideas...

I believe our loved ones spirits are always around us. Just be open and know that there is nothing to fear. Remember little things he always did or said, sometimes I see silver dimes all over. I find them in the oddest places, always dimes though. I believe this is because my fiancé who passed used to collect dimes. Things like this can make you more open to them around us. GOOD LUCK.

The only thing that you could do without bringing someone else over(could be a bad spirit!)
Is to seek help from a TRUE psychic medium. They are experienced in this sort of thing so be safe and go that route.
