Falling Down Under Anointing? - Religion

Please can someone shed more light on this topic. The church I attend, every anointing service, the pastor lays his hands on every single member of the congregation. Most people start falling. When I asked a deacon, he said they are falling under the anointing. I don't fall however Does that mean anointing no dey catch me? Lol. Have you experienced this, are there any Biblical references on this topic. Please share. Thanks
