Was in the hospital with my girlfriend's family whilst one of them got a check up. This hospital is a fucked up place.. as in the mental patients were sat in the waiting room talking to severely ill people which I found terrible. There was a overweight old guy, in his 50-60s who was clearly twitching, on a come down from whatever drugs just stood outside the door. He asked us, sweat dripping from his head 'what is the time?' so we gave him it, and went in. I went for a cig outside, and he asked me the same question twice. I got the fact he wasn't mentally all there but I got a feeling that although he had his issues he was harmless.. so I started chatting to him to take his mind off things. He was homeless.. did time in the army, and came back to find his wife had hung herself and his child in the bathroom. Spoke to me about it quite graphically, told me what he thought and felt when he saw it. Really felt for the guy.. I know he had his issues but he was cool. Spoke to him for hours, spoke about loads of stuff.. his drug addiction, things in his life etc. He was getting progressively worse and worse drug-wise, so I asked him what he had been on and he told me he sniffed a lot of speed and was coming down from sniffing a q, which had kept him up 8 hours. There was a woman bringing her 90+ year old mother in who was seriously ill, you could tell by her face. He then started getting reaaaallly paranoid, saying the woman was from one of his wards, and that they send people to watch him, to eventually take him back etc - I tried talking him down, which didn't help much but I soon found a way of distracting him. Although I knew he had mental issues, possibly a paranoid schizophrenic, I felt safe around him. So I went out for a couple of cigs with him, talking about deep shit but also laughing and joking. Came back into the waiting room, talking for a bit and this guy walks in dressed in a hospital gown. He looked really thin, pale as a sheet, horrible hair covering his face. Looked really fucking sick physically.. but when I looked at him it gave me this really weird feeling like I wasn't scared of him.. just his presence made me feel awkward and uncomfortable. Just by looking into his eyes it made me feel uncomfortable and on edge. So he came into the waiting room, and next minute the fella I had been speaking to all night starts freaking the fuck out whispering to me and my girlfriend 'he is fucking weird him. not right. don't look at him. don't speak to him'. But this guy wasn't really whispering (well, he thought he was) but he was loud and the other guy could hear him. He sat directly across from me, and as the guy was saying this I looked at him, and he looked at me and he had this weird smile.. not a genuine one as in he felt enjoyment from hearing what that guy thought of him and that he wanted to try and manipulate me into thinking im actually okay. He had this unique, creep look in his eyes. He then started looking at my girlfriend for a second or two, so I stared straight back at him (I know, stupid but sometimes I feel the need to do things and have never felt scared of anybody in these moments). He then gave me that weird smile again.. but I didn't acknowledge him.. I didn't feel like I could keep looking at his face - I had to look away even though I knew he was looking at me, which isn't normal for me. I didn't feel scared.. it was a different feeling.. more anxious. I honestly though to myself there is something straight up fucking evil about this guy and that he needed putting down. Then the guy stands up, comes over and sits right next to me. The guy I had been chilling with all night starts freaking the fuck out again saying 'just get out of here, ill distract him get out of here' - he clearly felt the exact same energy around this guy as I was feeling. So we carry on speaking like he isn't even there, and the guy randomly starts laughing and says 'I though I was Hitler walking the streets of ****' (can't remember where). But his voice.. everything around him just gave me this uncomfortable weird feeling.. even just thinking about it properly now it's giving me goosebumps. But yeah, the slightly crazy guy who was clearly troubled but I could tell was a genuinely lovely person, ended up making an excuse for us to leave and we did.. but when we were walking away he looked at us and his eyes showed how uncomfortable he felt around him.. he was honestly scared and so agitated. I didn't want to leave him but he basically forced us to, for our own good. I will never forget that night.. someone must be pretty fucking crazy and evil if a crazy person can recognise it and feels so uncomfortable in his presence.
