elevator last night

ok, so we were going to see a relative at the hospital last night. well we went to the wrong building not knowing the right building was right across a little road. so we get on the elevator and push 4th floor. the doors close and it takes forever to go up. finally it goes up and it goes straight passed the 4th floor and keeps going and going til it got to the tenth floor. we push the 4th floor button again and the door closes and it goes down to the 6th floor. when the door opened there was no one around then suddenly a older lady got in the elevator with us. idk but when she got in there everyone got a weird hair rising feeling. she pushed 4th floor also and up it went back to the tenth floor. soon as the doors opened on the tenth floor we got out that elevator. we got on the one next to us and again pushed 4th floor and nothing, it went down to the first floor, so we got out of there quick.
