Help, what are these stains that keep appearing on my bedding?

am definitely having this same problem, and it seems to have started about 6 months ago. But not bed bugs, because it happens in my bed, hotels, when I've visited my parents, and while sleeping in the car. Always only on my pillow and not my husband's or my kids or my parents. I've started trying to link medication usage, hair products, congestion... I've come up with nothing. I don't wear makeup to bed at all, no hair products. The only thing I can think of is some type of ear drainage. The photo I attached was last night while staying at my parents home, though the stains are often worse than this.

couldn't get the pic to post...

Hello, has anyone figured out what this can be? Its not bed bug droppings. The stains appear only on my pillow, not even my blankets. Hair is not dyed or anything. Can someone please help, honestly starting to get freaked out.

The same things has been happening with kids. My oldest who is 10 yrs old sheets seem to stain the same color as yours but the 4 yr old is different and its weird.

Mr Thomas

me too facing same problem since 2 weeks

I'm really scared what could it be

I recently one month ago changed my shampoo and conditioner. I'll again use old one and let me see the difference

again I'll be back on this forum

I have read so many of these queries about lines and patches on pillow cases and have really searched and searched for a possible answer. The only reasonable one I have seen is that it is iodine in your sweat. It is reacting to anything starchy in the linen and as you move it will appear in blotches or lines. Maybe ask you GP for an iodine sweat test??? The chemical test for iodine is that it turns purply black when mixed with starch. Do some of you use starch in your washing or spray starch?

I also have been perplexed by the stains. For a long time, I thought it was my eye mask that I wear when I sleep that was leaving the marks. Then, I thought it was hair dye bleeding.

Could it be a reaction to a negative element in your body? Like an allergic response? You eat or drink something before going to bed and, in allergic response, it excretes something via your scalp.

Could it be a result of chemical exposure? I ask this because I have only seen it in an apartment with a gas heater and cooking stove. Maybe the stove is leaking small amounts of gas?

I'm intrigued by the person who suggests taking a sweat test to identify the amount of chloride in your system. Sweat tests are used to identify cystic fibrosis, a lung disease. I first saw the marks on my pillow sheet about two months after recovering from covid, which caused damage to my lungs. Could the lungs be excreting something via drool that leaves the mark? Do you have asthma or a lung issue? Could that be a commonality among us? I believe the answer to the question of what's leaving the mark is identifying what we all have in common.

It is not bedbugs. the stains look nothing like bed bugs.

This has been happening to me for the last three weeks as I have been on a road trip. I am traveling with my husband. These marks only appear on my side of the bed, not my husband's. And only up around the head and shoulders area. They are very similar to yours only a little bigger/ darker. I am sure that it has something to do with what laundry detergent they are using because it does not happen at every hotel.

I really doubt a lot of hotels only have bedbugs on my side of the bed and only on the top 1/4th. Plus bed bug marks are reddish brown, not purplish black.

I do not wear makeup at all. no jewelry in the bed... not even my wedding ring. No moisturizers or creams. It's a mystery that has me very concerned.

literally same thing! i changed my sheets and went to bed, woke up and saw it on my satin pillowcase and somew parts of my bed. like a streaks/watermark black. i put water to rub it off and it didnt come off. now its just fading by itself??? the marks are disappearing and i have NO idea. the ones on the bed itself has disappeared.

hi, i am from france and this is happening to me too. all my pillows cases and now my pillows too have blue/purple/black stains and they don't go away after washing, i don't wear make up, i don't color my hair or anything. i use laundry detergent with no chimicals since forever, i don't know what it is and since it doesn't stop i start to worry.
