Carnival of Souls is about a woman who apparently dies when the car she is in goes off a bridge, but then she emerges from the water... She goes to her new job as a church organist, but when she starts to play bizarre music, the pastor fires her... then weird things start happening to her, and she gradually comes to realize that something very strange happened to her in that accident.
The women is played by a very attractive blonde named Candace Hilligoss, whom I had never heard of before.
but I've heard that it's very good. I'll have to see if I can find a copy.
