Meaning of sentence「最近よくじわ怖スレ見てるからビビりになってる。」


I'm self studying Japanese and I read horror stories to build my reading
skills. Recently I came across this sentence that I can't figure out:

> 最近よくじわ怖スレ見てるからビビりになってる

I can't understand what do じ, わ, スレ mean in this sentence. Please, help me
understand it.




> 「[最近]{さいきん}よくじわ[怖]{こわ}スレ[見]{み}てるからビビりになってる。」

This must be a tough one for someone teaching himself Japanese as it is
studded with slang.

「じわ」: Short for the onomatopoeia 「じわじわ」 = "gradually", "slowly", etc.

「怖」: Short for 「怖い」= "scary"

「スレ」: Short for 「スレッド」 = "thread (in an internet forum)"

So, 「じわ怖スレ」 means "threads that make you feel scared slowly" if that makes
sense. The threads are filled with the type of scary stories that get you
scared not instantly but rather gradually.

「ビビり」: Slang for "a timid person", "coward", etc. You will encounter the verb
form 「ビビる」 (= "to be afraid") even more often.

My rough TL will look like:

> "I have become somewhat of a wimp because I often read the じわ怖スレ."

「見る」 can be used to mean "to read".
