"Yesterday was such a surreal day & not sure it's really soaked in."


and wondered what does "not sure it's really soaked in" mean. Does it mean if it is real?
is it a slang or idiom?

thanks!

It means she's not sure whether she's fully understood (or appreciated, processed, assimilated, integrated) all the consequences of what happened.

I am not a teacher.

The meaning is clearly what Raymott says, but in BrE I've only ever heard 'to sink in', not 'to soak in'.

 

[didagwen]

Yeah, probably that's why I can see the meaning "sink in" in the dictionary but "soak in".

 

[didagwen]

So is it common to say it like that in the U.S.?

 

[MikeNewYork]

In the US, we would use "sink in".

Probably the person just chose the wrong word. Soak/sink are pretty close. I could see someone doing that unconsciously.

Social media entries are often written at speed, so such mistakes are common.
