Hi guys, I used to do some entry-level freediving when I was a kid. Well, now I'm 27, didn't train since then. I went to 25m swimming pool tonight and tried doing some laps underwater. I went for first 25m very calm and nice, turned, kicked the wall and begun doing another 25m. All fine, I reached end of the ramp on the bottom - 37.5m mark. Next thing I remember is kind of unreal. It felt like sleeping and being in some dream. My body was shaking, I didn't feel any pain, I didn't feel I needed to breath. It lasted for some time. Hard to describe, but it was very not coherent. Dreams are usually like that - you figure out you are somewhere and you have no idea how you managed to get there and what actually happens. That's how it felt, no anchor to reality. My subconsciousness somehow pulled me out of water next to 50m wall and only after around 2-3 seconds I started getting back to real world. Then I felt I had little bit of water in my mouth or larynx, but only some, maybe table spoon or two. I couldn't just start breathing normally, something was not working. Like my throat was clogged. I was really calm, just taking my time slowly. 10-15 seconds later it was ok. Whole thing was very weird. Shaking was kind of uncomortable, but not painful. I think it wasn't my diaphragm shaking, but legs and arms. I don't remember swimming last 12.5m. Is that how blackout feels?

.Actually you didn't blackout but you were extremely close to it. These strange unreal feelings as well as shaking (it's called samba) were caused by severe hypoxia. If it was a blackout you would be found on the bottom of the pool. You are lucky you're alive. You surfaced only because you reached the wall of the pool. If it was 5m further you would loose consciousness under water. You should NEVER dive without supervision!
You're very lucky to be alive. There is a disconnect of memory when you black out, or are knocked out and maybe when you fall asleep. The memory from the last 7-8 seconds doesn't get stored. What probably happened is you went for the wall and blacked out after grabbing hold. One lucky fellow. The dream as you gain consciousness is 'normal'.
Shit! To be honest I never push boundaries. It was going so well, I thought that wouldn't be such a big deal to finish the 50m. I didn't hyperventilate, it all seemed very ok. Well, won't happen again. Thanks for your responses guys.
What breath up technique are you using? I am completely new to freediving and was surprised to find out that I had been hyperventalating in my dry statics with deliberate slow breathing.
Learn to know your bodies fits!
Everyone is different but I find 4 to 5 twitches then I have to go up soon as they stop!
I can push it 2 minutes after that but last time I did that I woke up after my buddy pulled my head out of water!!!
Besides spearfishing I take my time n go up for a breath n dive down that way if I need time once I shoot I can push myself a little!
I'm 62 and have a wear and tear back pain problem. This resulted (in the past) in severe cramps. Over the years I found that especially cold weather while canoe camping again caused cramps during the night, when muscles are relaxed. I've just joined this forum as I'd like to try spearfishing but after reading this thread but nowl I'm not so sure anymore. Plus the thought that holding your breath may decrease blood oxygen levels thus resulting in yet more cramps? Any thoughts? Thanks in advance
Actually you have to hold your breath a long time before O2 starts to drop much. In a typical real-world recreational breath-hold dive you will resurface long before O2 drops.
