The Spaghetti Warehouse is one of Houston’s most notoriously haunted buildings – but don’t take our word for it, find out for yourself during the Ghost Hunt Lock-In. Unlike some spirit hunts, the lock-in allows you to bring your own equipment and take your own readings and photographs as you try to catch one of the many rumored lingering spirits. Over the course of the adults-only event, tour members will discover a tomb built right into the side of the bayou, visit some paranormal “hot spots” and try to detect odd psychic disturbances. Tour leaders will also conduct some group searches. 9 p.m. September 18. 901 Commerce. For information, call 713-222-9255 or visit www.discoverhoustontours.com. $50.
