‘A lot of parents get worried about imaginary companions and strange experiences. Unless there’s real distress, don’t worry.’ Ceryn agrees. ‘Children could be more receptive to seeing spirits because they haven’t been in this world as long as we have,’ she says. ‘It’s a bit like when we go on holiday and the memories are still fresh, and then they begin to fade. Children still remember the other world. Also, they haven’t yet been told that they shouldn’t be seeing these things.’

Ceryn advises that if your child is talking about seeing ghosts, try not to dismiss them, but also try not to overly encourage them either.

‘It’s a fine balance. Feel free to ask them a question about what they experienced, but then just move on and leave it. Try to keep it as a really normal thing and don’t give it too much attention.’

However, not everyone is ready to welcome spirits into their home. If you’re concerned you have some visitors you don’t want, there are some steps you can take to protect yourself.

‘If you’d like the spirit to leave, say firmly out loud: “You are not welcome in this house. These people are not your people”,’ Ceryn recommends. ‘If you can, ask a grandparent or someone else that you trust, who has passed, to look after your child and protect them from spirits.’
