Ultrasound is a very helpful tool that give parents an incredible glimpse of their children while they’re still in the womb. Through this technology we can tell the unborn’s gender and it can help save lives in many aspects. But who would thought that this device can also give us an unexplainable eerie moment, just like what happened to a couple from Sidcup, London.Parents Jon and Lindsay McHale got the biggest surprise of their lives when they gave their unborn baby “Madison” an ultrasound scan. But it isn’t just the baby girl who appears, because something unearthly also showed up in the 4D scan. Is it a ghost or a guardian angel?
