Tarot Cards Under Pillow in Shared Bed?

so i’ve been wanting to get into tarot for a long time and overall delve into my spirituality more. i have read many times to sleep with them under your pillow for 7 nights to attune to them. i don’t know how much it all matters but i tend to rotate between sleeping at my own house and at my partner’s home where we share a bed. would it matter where i slept with them so long as they were under my side? it seems silly but i want to do this right and make sure that my partner’s presence in the bed wouldn’t negatively affect the process. thoughts? advice is appreciated! thanks
