Demon encounter? Need advice

Around 11 pm easter night I was praying like I normally do and drifting to sleep. Around 11:20 pm my four and six year-olds monitor started going off. my four-year-old was having a night terror. My husband did not realize this and was frustrated when he would not go back to bed. I decided to go in there and immediately felt the need to pray over him. They have a bunkbed. I sat on the floor, took my son‘s hand and prayed Psalm 91. when I was done praying, my six-year-old on the top bunk who was sleeping facing the wall whispered “mommy look behind you.” I wasn’t sure if I heard him clearly so I had him repeat himself and he said “mommy look behind you.” I stood up, asked him to repeat himself one more time to be sure that’s what he said. I turned around and I felt a presence pass through me as I went to leave the room to get my husband. I felt hot tingling and disoriented, and I heard it speak to me and tell me “I told you to turn around.” Has anyone experienced something similar to this?
