My dad passed away on 01/25/2018, during a time when I was also going through other difficulties which he did not know about, and I believe my family has been under attack in spiritual warfare. It was a while before I had my first dream; I have had 3 to date.
#1: (pretty self explanatory to me) He is sitting in a hospital bed, ripping IV's and oxygen mask off, stating "I feel great, I'm out of here." I know he is healed and whole.
#2: My family and I are in a huge warehouse-type building for grief therapy. People are assigned a room to attend depending on their occupation. When "maintenance" was announced, I saw my dad come in. He approached me with a huge smile and I said "What are you doing here?" to which he replied, "I don't know, I'm not grieving, I feel great." He asked where my mother was and said he would talk to her in a minute, but he just wanted to see me and give me a big hug that lasted a long time, and even in my dream I wondered what it was about.
Between #2 and #3, I heard a sermon at church where the pastor stated that Jesus knew something was coming and prayed non-stop, at which point he looked at the congregation and stated that some of us know something is coming and that we need to engage in spiritual warfare.
#3: We are at my parents' house and my dad is standing just inside the front door. I asked him what he was doing there, and he said he just wanted to see me again and give me a hug that didn't last as long and even in my dream I begged him to stay so I could hug him longer. I was thinking to myself in my dream "don't wake up, don't wake up."
