Ghosts and ghouls of all shapes and sizes are rattling their chains across the country tonight as bonfires and fireworks light up the 31st of October sky.
The annual Hallowe'en celebration of sorcerers and sweets has long been the subject of safety warnings as adults and children alike celebrate the ancient Celtic pagan festival.
Gardaí have made several seizures of illegal fireworks in the run-up to Hallowe'en and as in previous years, have issued warnings about the serious dangers associated with using fireworks.
The warnings were echoed by safety bodies with the National Safety Council calling the mixture of bonfires and fireworks are a "deadly combination".
The ISPCA have called on pet owners to keep their animals indoors tonight and have said that some vets had prescribed tranquillisers for pets frightened by the sounds of exploding fireworks.
There have, as yet, been no reports of out-of-control fires or injuries sustained by the misuse of fireworks.
Hallowe'en marks a night on the Celtic calendar in which winter begins and the boundary blurs between the living and dead.
