Deceased aunt is telling me to look for money!?

To make a long story short, in May my uncle ped away, I am the sole heir to his estate, which includes a condo and the furniture. His wife ped away 1 year before him, I was VERY close to her, both of them raised me as their daughter. I went to their family meaning their neices and nephews asking for help to pay for his funeral expenses. Everyone said they didn't have anything to help and some flat out said since I got left everything it's my problem. I cried that night and my aunt came to me in my dream and said "It's money there, you're just not looking hard enought", so I begged her to tell me where and she said "I can't say it any louder or they'll hear me!" I just want to know am I losing my mind or can the deceased talk to you? This is serious and I'm not making this up. When my uncle ped he knew of my financial situation, I am 28 years old with 4 children and work to pay my bills, he only has $2,000 in the bank. Has this ever happened to anyone else?
