Should Christians Celebrate Halloween

Blessings to all, before the coming Holiday i wanted to address a concern I 've had about  Halloween there seems to be a growing trend in the body of Christ with some churches celebrating this pagan Holiday. there is a church that turns there sanctuary in to a haunted house in the name of evangelism, the problem i have with this is Jesus never said set up haunted house to win the lost, he said go into every nation and PREACH the gospel and make disciples. Mark 16:15. If Christians really knew the origin and the spirit behind Halloween would they celebrate it.
