I dreamed my friends vanished on a dark bus trip, chased by a creature in blue

TI am a 18year old girl, I got this dream where I was going on a bus with my friends and then many small things happened then suddenly at a night time the bus stopped it was really dark then everyone was told to get off the bus, after we got off I asked my friend and a friend of mine replied he said it was to have some rest also to repair the bus then I said ok then after sometime we were near a place where there were steps then my friends were taking and one of my friend point at a house and said we have to go rest there. It was still really dark when it was happening, suddenly someone said a friend is missing, so I panicked because I remember I heard sound on the bottom of the steps so I told my friends I am going down to check stay here but I don't know if they heard because they were talking then I went down as i went in i saw a creature like something the it burn a blue coat, it looked just like our uniform, I got scared so i ran back to my friends to say this, as i ran up I could feel the creature behind me, but as i came up the stairs i couldn't find them also since it was dark I thought they might have went to the house they mentioned so i ran there still the creature chasing me, but they were not in the house too so I ran back to the steps since i thought they might have came to check on me, since the creature was chasing me I thought i could go down the steps and find them then I am safe but after i went down the stairs there was no one and I am trapped I felt anxious just then I woke up. Similar dreams have been appearing time to time similar to this, I wake up just at the time where I know I can't escape anymore or something bad happens.
