I can appreciate what you say because I remember years ago how lovely that is from when my uni housemate was away one weekend and her cat came in my room.I hate the sleep pillow sprays, sorry. They do nothing for me and always have lavender, which I love but makes me happy and not sleep at all. I'd be more likely to want to get up and dance round the bedroom.
My sleep aid is Freya the cat, she sleeps on the bed with me and I just gently stroke her and fall asleep.
I do quite like the sprays, though, I must admit. I don't use them all the time and maybe it's a placebo effect I get but if it works in one way or another, I'm up for it! It's bloody awful when you can't get off to sleep or keep waking up in a panic (as I have done at times throughout my adult life).
Anyway, I'm going to think about getting a cat again now! You've set me off!
