The Haunted House Romance

The night begins with you setting the mood with dim lights and Halloween decorations. Use props from around your house or DIY a few. Set out a table with your partner’s favorite snacks, and a couple of drinks.
Once the stage is set, indulge yourselves in thrilling ghost stories, with each room designated to a different story. Alternating between storyteller and the one who gets spooked can make it a fun experience. Create a climatic finish by pointing out the 'spooky ghost' you spotted earlier in the corner.
The night ends with both of you escaping the haunted house - you can make your way to your room: the 'safe zone'. As a reward for braving through the night, you could give each other a relaxing massage with a touch of intimacy.

Collect some Halloween decorations, or make your own using DIY tutorials online. Choose some spooky candles, cobwebs or makeshift ghosts. A dimmed lighting setup will help set the right atmosphere.
Prepare snacks and drinks that your partner loves. Make sure you are well versed with a few ghost stories which you will be narrating throughout the night.
Find suitable, comfortable clothes that can allow easy transition to a relaxing nightcap towards the end. Create a playlist of eerie music to play softly in the background.

Ensure your partner is comfortable with the theme. Some people might genuinely not like spooky stories, and it’s crucial you consider their feelings and preferences first.
Make sure the room's temperature is comfortable given that it’s the month of October and could get cool indoors.
Make the ghost stories and spooky pathway fun rather than too eerie or scary. The aim is to have a fun-filled romantic evening. You can include some funny anecdotes in your stories to keep it lighthearted.
