Is this weird after-effect of weed normal?
So I'm a semi-regular smoker (I go on and off every couple months) and this has been a fairly recent occurrence. A month ago, I smoked a lot and I had this weird sensation of everything pulsing and it's hard to explain. It wasn't necessarily bad, just confusing, and it mostly went away the next day. Then this weekend I basically spent 72 hours straight high. The first it took a few hours (and more hits) before I had that weird pulsating feeling, and the next morning I still felt it even though I was (pretty sure I was) stone-cold sober.
I smoked all day and the feeling kind of lingered. Then the next morning I took maybe two hits and I felt it all day again! I smoked again last night and I felt better about it when I was high but when I'm sober and it's happening it's just wrong.
To describe the feeling, it's like I can feel everything happening multiple times. Like, when I fold my legs it feels distorted like I have five legs where I have one and it's just happening over and over again. I'm very confused and uncomfortable and it's hard for me to do things. Is this normal?
