Here are some material I copied with experiences of anointment
It was a special spiritual experience. I was in the kitchen alone. All in may family were sleeping. I think I was praying or was it that I was meditating on spiritual matters. I had my eyes closed and it felt like I was lifted up from the floor. I did not open the eyes but I think I remained on the floor. Just a feeling of flying up to heaven to the presence of our heavenly Father. It felt like he was by my side behind me may be about 5 meters. There I was flouting in the space. At that moment or was it shortly afterward, I was like looking down on earth, on the green gras and treas and all got gray before my eyes. I felt like I lost my connection to the paradise hope. There I was looking down on earth and I felt that I am loosing my connection to earth. Then the vision stoped and I opened my eyes, and I was back on earth. I wanted to stay in that vision, or it to be repeated, but it haven't. But it was nice, I liked it. From that time on ward I started to expect that I'll be anointed. I did not understand that this was the anointing. But the desire to be in paradise disappeared. Then always hearing or reading about God's kingdom I unwillingly was paused in breathing and taking a deep breath. The more I doubted the more something squeezed my heart when I encountered scriptures concerning the anointed in my personal Bible reading. Just before the anointing I had read through all the Bible in about 3 months. Then I started to read it once again and where apostle Paul writes "we". Before I automatically made the conclusion that he refers to the anointed and not to me. But after my anointing, rereading these passages felt so familiar, like he is meaning me personally. So all this built up a confidence in me that the holy spirit is telling me that I have been adopted to be God's spiritual son. When I finaly got convinced, then almost all such testimonies of the holy spirit ceased. Propaply because I am already convinced and therefore there is not a need to convince me again. But these testimonies happened surely hundreds of times reading the Bible, because the matter is touched so often in the Bible.
Actually the Watchtower explains that the holy spirit affects the anointed in that way when they read scriptures that talk about them.
Next is of a brother who was in fulltime service for long times. In his life story he tells how he got anointed, it is a interesting and quite long story.

The next article is written by a former Jehovah's witness missionary, who confesses to be anointed and he tells some experiences of other anointed.

8. The calling of each one seems to be radically different, one from another. Several people, some personally known by me, have had unique experiences which can best be described as the ‘promptings’ of God’s holy spirit. Two of these were on the verge of suicide, but after they prayed, (in both cases) they sensed an inner peace, a reassuring calmness that came over them. On the following day, they (each, separately) had the unexpected visit of a Christian to encourage them, and to study the Bible with them. Another unique example is that of a young man who had just returned from the military. He was not a Christian, but out of curiosity he went (with some of his friends) to a ‘Billy Graham’ Crusade. On his way to the platform, God’s divine plan of salvation "flashed before his eyes." None of his friends shared this experience. It was unique to him. Some time later, he got a Bible and began to read it, but could not understand what he was reading. And so he prayed about it. Shortly thereafter, he came across a book, (Divine Plan of the Ages), by C. T. Russell, and to his great amazement and utter surprise, its contents were exactly what had "flashed before his eyes" a few years before.
Two other examples are of persons who had been Christians for many years. One day, each one felt touched by God’s holy spirit, and realized it meant a relationship with God, (i.e., son-ship).
Yet another example is that of my wife. As a young woman, she felt overwhelmed by life’s difficult experiences and regularly went to a nearby hill to meditate and pray. "One day, suddenly," she relates: "I felt surrounded by God’s love, reassuring me that he really cares for me." My own situation is that, from a very young lad, I have always felt very close to God. But when I understood what a relationship with him really meant, it was only then that my feelings of being God’s son were confirmed to me by his spirit.
