The phenomenon of a woman attempting to speak to a sleeping man after sex.

Deep heartfelt words of union, spoken in bed. Sometimes nonsensical in the practical world but making perfect sense to the partners at this moment.

When one is pretending one has a partner (normally fantasisical), in the bed with them and talks to the pillow. It is also used to describe when two people chat pointlessly before/after sex.

Talking to someone like a friend, family member, boo just anyone really while your laying your head down on a pillow

Contrary to the top definition, Pillow Talk actually has two connotations.

The first connotation is the most thought of one. It's intimate talk with your romantic partner in bed, either before or after sex (but usually after). It is usually at this moment where all personal thoughts, desires and troubles are revealed in a candid tone. Those thoughts you've locked away during daytime are now front and center, completely transparent to your partner. Pillow talk can really be anything, it can be goofy or serious, but the main distinction is that everything spoken is 100% candid and true to themselves. No pretense, just you being you.

The second connotation is less restrictive and applies more generally. Here, Pillow Talk is referring to the intimate deep conversations between two or more people within a platonic relationship (e.g. friend, colleague). It often takes place in a location that stimulates bonding and conversation. For example, a literal sleepover with your friends can spur pillow talk, or a night out at a pub with your bros. Again, same meaning applies here. The conversations are usually very candid and lasts for hours, no pretense whatsoever.

Overall, pillow talk is a crucial component in relationships and its effect can be very therapeutic.

Intimate communication before or after having sex with your partner

Refers to a pleasant conversation that you share with a buxom gal while your face is buried between her ample tits. Extra brownie-points if you remembered to "mow the lawn" right beforehand, so that the chest-sharing chick just feels satiny-smooth jowls in her cleavage rather than sandpapery raspies or prickly/tickly hairs; besides, freshly-shaved cheeks are ultra-sensitive, and so you get a "past heavenly" feeling from softly rubbing your face against a girl's "girls".
