La Carafe, Houston's oldest bar, is described as haunted due to unexplained occurrences such as flickering lights, unexplained footsteps, glasses shattering, and objects moving on their own. Reported spirits include "Carl," a former bartender, a sinister man standing by an upstairs window, and a woman in white who allegedly pushes people down the stairs. Some visitors have also reported hearing singing or a ball bouncing, and a former owner's girlfriend mentioned a man who always stands in front of the mirror, according to YouTube. Visitors report seeing apparitions of a man in the upstairs window, a woman in white, and even the spirit of Sam Houston sitting at the bar, says US Ghost Adventures. Sounds include unexplained footsteps, glass breaking, a woman singing, a little boy's ball bouncing, and the ghost of former bartender Carl calling out, "Last call". Guests have felt a tap on their shoulder in the men's room with no one there, or have felt compelled to look back at the bar from across the street to see a man watching them from an upstairs window. Reports include a vintage cash register that opens and closes by itself, the jukebox changing songs without permission, and the infamous woman in white pushing people down the stairs.
