Unusual Presence

Last night, i woke up from bed hearing a voice (i do not know or understand what it said) and suddenly feeling that there is something scary and supernatural at my right side. I did not see it but i felt an unusual dark presence. I did not dare open my eyes or look at it. I sang a hymn in my mind but since i could not remember the lyrics I hummed. Then i sang the song i always hear at the end of the healing mass i watched when i was younger with lyrics that only call on Jesus name repeatedly. I continue singing in my mind until i feel its evil presence fade and I felt the feeling of the room felt normal again. I think it was not a dream because i was in the same position aware the whole time until I went back to sleep again.
